Scientific results and innovative ideas

· A new direction in supersymmetric models of elementary particles, based on the inclusion of semigroups is proposed (book, thesis). The concept of semisupermanifold having noninvertible transition functions (satisfying higher von Neumann regularity) is introduced, and its deviation from being an ordinary manifold is given by a newly defined variable, obstructedness. Based on this idea, the novel notions of category regularization, regular topos, regular functor, higher regular braiding, regular Yang-Baxter equation and regular module, regular algebra and coalgebra, regular graded algebras are presented, and their role in topological quantum field theory is outlined. Even- and odd-reduced supermatrices are introduced and considered on a par, being complementary in terms of the newely obtained Berezinian addition formula, and are unified into a kind of "sandwich" semigroup. A special subset of odd-reduced supermatrices represent higher order rectangular bands for which new generalized "fine" Green's relations and egg-box diagrams are constructed. One-parameter semigroups of idempotent odd-reduced supermatrices and corresponding superoperator semigroups are introduced and studied by the new semigroup × semigroup method. The linear idempotent superoperators and exponential superoperators are mutually dual in some sense, and the first gives rise to an additional noninvertible non-exponential solutions to the initial Cauchy problem. A novel permanent-determinant symmetry is found for even complex superplane. It is shown that the corresponding counterparts (per analogs) of the cross ratio, distance and harmonic set are invariant under the introduced per mapping, a special noninvertible subset of the fractional linear transformation. The per analogs of the Laguerre formula for distance and Schwarzian derivative are presented. An additional superextension of complex structure is uncovered, which is noninvertible and can correspond to another (odd) superanalog of Riemann surfaces and to the counterpart of superconformal-like transformations which twist the parity of tangent space and their nonlinear realization, which together with the ordinary ones form the superconformal semigroup having special unusual properties. A unique formula connecting berezinian, permanent and determinant is obtained. From a physical viewpoint, the above conceptions can lead to semistatistics, being von Neumann regular analog of the ordinary statistics.

· Quantum groups: a generalization of the Hopf algebra is introduced by relaxing the requirement for inverses of the generators of the Cartan subalgebra, which leads to a regular quasi-R-matrix structure. The classification of 6-vertex constant solutions to Yang-Baxter equation over Grassmann algebra is presented, including noninvertible ones which correspond to von Neumann regular R-matrix. The actions of universal enveloping quantum algebras on quantum planes (also of arbitrary dimension) are found. A novel double-graded quantum superplane and corresponding double-graded Hopf algebra are presented.

· Singular theories with degenerate Lagrangians are formulated without involving constraints using Clairaut equation theory and the corresponding generalized Clairaut duality. A new antisymmetric bracket (an analogue of the Poisson bracket) describing the time evolution of singular systems is built. A novel partial Hamiltonian formalism is constructed. It is shown that a singular theory can be interpreted as the multi-time dynamics.

· Nonlinear gauge theories: a generalized approach to nonlinear classical electrodynamics and supersymmetric electrodynamics is suggested, which takes into account all possible types of media and nonlocal effects, and is described in both Lagrangian and non-Lagrangian theories. First steps in the formulation of a general nonlinear conformal-invariant electrodynamics based on nonlinear constitutive equations and conformal compactification were made.

· Gravity: constitutive equations for nonlinear gravito-electromagnetism and an exact form of the Maxwell gravitational field equations are obtained. A general approach to describing the interaction of multi-gravity models in space-times of arbitrary dimension is formulated. The gauge gravity vacuum is investigated in the constraintless Clairaut-type formalism (as in QCD). A special fermionic lineal gravity model which differs from standard supersymmetry is presented.

· Quantum computing (book IOP, FrontMatter): a new conception of quantum computing which incorporates an additional kind of uncertainty, vagueness/fuzziness, by introducing a new "obscure" class of qudits/qubits, is announced. A superqubit theory in super-Hilbert space is reconsidered, and a new kind of superqubit carrying odd parity is introduced. A new kind of quantum gates, namely higher braiding gates, is suggested, which lead to a special type of multiqubit entanglement that can speed up key distribution and accelerate various algorithms. A novel visualization of quantum walks in terms of newly defined objects, polyanders, is also proposed.

· Polyadic structures (book IOP, FrontMatter): polyadization, i.e. exchanging binary operations with higher arity ones, is proposed as a general new approach to the algebraic structures used in physics. A new form of the Hosszu-Gluskin theorem (giving the general shape of n-ary multiplication by the chain formula) in terms of polyadic powers is given, and its q-deformed” generalization is found using the newly introduced quasi-endomorphism. A polyadic analog of homomorphism, or heteromorphism, a mapping between algebraic structures of different arities, is introduced, which leads to the definition of a new kind of n-ary group representation, multiplace representations, as well as multiactions and a polyadic direct product. The arity invariance principle, a manifest expression of algebraic structure in terms of operations independent of their arity shape, is claimed. The relations of the von Neumann regular semigroups and the Artin braid group were found, and a higher arity generalization gave the polyadic-binary correspondence, which allowed the definition of the following new structures: higher braid groups, higher degree analogs of Coxeter group and Artin braid group. The following were also uncovered: unusual polyadic rings and fields (which can, remarkably, be zeroless and nonunital) having addition and multiplication of different arities, polyadic integer numbers and p-adic integers, polyadic convolution products having multiplication and comultiplication of different arities and their corresponding polyadic Hopf algebra and n-ary R-matrix, polyadic multistar adjoints and polyadic operator C*-algebras and Cuntz algebras. The polyadic analogs of the Lander–Parkin–Selfridge conjecture and Fermat's Last Theorem were formulated. It is proposed that mediality as a principle is more natural, unique and universal than commutativity in generalizing the latter to n-ary algebras (in the binary case commutativity directly follows from mediality). This is called the commutativity-to-mediality ansatz, which is applied to obtain almost medial n-ary graded algebras, a new kind of tensor categories, polyadic nonunital "groupal" categories with "quertors" (analogs of querelements in n-ary groups), "medialed" tensor categories and querfunctors. A principally new mechanism of additional "continuous noncommutativity", governed by a special "membership deformation" of commutativity for algebras with the underlying set as obscure/fuzzy set, is introduced. Using the membership deformation factor together with the ordinary graded commutation factor, the almost commutative graded (n-ary) algebras and Lie algebras with double commutativity are obtained, and their projective representations are studied. As a first step towards a the polyadic algebraic K-theory, the Grothendieck construction of the completion group for a monoid is generalized to the case, where both are of different, higher arities. As opposed to the binary case, an identity is not necessary for the initial m-ary semigroup to obtain a class n-ary group, which in turn need not contain an identity. A new (infinite) class of division algebras, the hyperpolyadic algebras, which correspond to the (only 4) binary division algebras R, C, H, O (reals, complex numbers, quaternions, octonions) are defined. A polyadic analog of the Cayley-Dickson construction is proposed, and a novel iterative process gives "half-quaternions" and "half-octonions". A novel polyadic product of vectors in any vector space is defined, which is consistent with the polyadization procedure using vectorization. Endowed with newly introduced product, the vector space becomes a polyadic algebra which is a division algebra. New polyadic algebras with higher brackets which have (as opposed to n-ary Lie algebras) different arity from the initial n-ary algebra multiplication, are introduced. The sigma matrices and the Pauli group are generalized to higher arities. Using them, a toy model of one-dimensional supersymmetric quantum mechanics was constructed, as a first example of polyadic supersymmetry, which is specially extended in a way different from the new multigraded SQM previously proposed.

· DNA theory: a new characteristic of nucleotides, the determinative degree, which is proportional to the dipole moment and the weight of hydration site, is unveiled. The physical characteristics of nucleotides such as dipole moment, heat of formation and energy of the most stable formation are newly computed by advanced methods. The concept of a triander is set up, which leads to a new method of visual sequence analysis and identification using DNA walk diagrams.
