In this work we have generalized the super KdV equation into a multicomponent super KdV equation. It is shown that the system
is bi-super Hamiltonian. The third super Hamiltonian in the multicomponent super KdV hierarchy is obtained and the corresponding
first and second members of evolution equations are given.

Starting from the full group of symmetries of a system we select a discrete subset of transformations which allows to introduce
the Clifford algebra of operators generating new supercharges of extended supersymmetry. The system defined by the Pauli Hamiltonian
is discussed.

The symmetric fractional derivative is introduced and its properties are studied. The Euler-Lagrange equations for models
depending on sequential derivatives of type are derived using minimal action principle. The Hamiltonian for such systems is
introduced following methods of classical generalized mechanics and the Hamilton’s equations are obtained. It is explicitly
shown that models of fractional sequential mechanics are non-conservative. The limiting procedure recovers classical generalized
mechanics of systems depending on higher order derivatives. The method is applied to fractional deformation of harmonic oscillator
and to the case of classical frictional force proportional to velocity.

We construct a family of infinite-dimensional quasigraded Lie algebras, that could be viewed as deformation of the graded
loop algebras. Using them we obtain new series of integrable Hamiltonian systems on semisimple Lie algebras and their extensions.

The conservation laws for second order linear equation with constant coefficients on braided linear space are derived. As
an example we study conserved currents connected with symmetry operators for scalar and spinor wave equations onq-Minkowski space. Then we formulate set of conditions for integral over spatial dimensions and use the postulated integral
in construction of constant of motion for arbitrary conserved current onq-Minkowski space.

We study systematically the general properties of theB-extension of any integrable model and its properties as Hamiltonian structures etc. We clarify the origin of “exotic” changes
in such models. We show that in such models there exist at least two sets of non-local conserved charges and that the “exotic”
charges are part of this non-local charge hierarchy.

The deformation equation and its integrability condition (Bianchi identity) of a non-(co)associative deformation in operad
algebra are found. Based on physical analogies, two ideas ofcogravity equations are proposed.

The models described by fractional order derivatives of Riemann-Liouville type in sequential form are discussed in Lagrangean
and Hamiltonian formalism. The Euler-Lagrange equations are derived using the minimum action principle. Then the methods of
generalized mechanics are applied to obtain the Hamilton’s equations. As an example free motion in fractional picture is studied.
The respective fractional differential equations are explicitly solved and it is shown that the limitα→1+ recovers classical model with linear trajectories and constant velocity.

The path integral quantization of contrained systems is analysed using Hamilton-Jacobi formalism. The integrability conditions
are investigated and the results are in agreement with those obtained by Dirac’s method.

We reintroduce a notation of Heine, which leads to a new method for computations and classifications ofq-special functions. The main topic of the new method is an involution operator on the set of allq-shifted factorials.

Some cases of extended Umbral calculus provide an underpining for deformed quantum oscillator models.
The Umbral calculus has been already formulated in Maple package. We shall present the first stages of the Mizar System usage
in formulating and checking the first principal statements of extended Umbral calculus.

The group of diffeomorphisms of a circle is not an infinite-dimensional algebraic group, though in many ways it acts as if
it were. Here we construct an algebraic model for this object, and discuss some of its representations, which appear in the
Kontsevich-Witten theory of 2D topological gravity.

We review known and we present new results on three types of short distance structures of observables which typically appear
in studies of quantum group related algebras. In particular, one of the short distance structures is shown to suggest a new
mechanism for the introduction of internal symmetries.

The essential parts of the operad algebra are presented, which should be useful when confronted with the operadic physics.
It is also clarified how the Gerstenhaber algebras can be associated with the linear pre-operads (comp algebras). Their relation
to mechanics is concisely discussed.

We introduce two types of algebras which include respectively the well known reflection equation (RE) and Faddeev-Reshetikhin-Takhtayan
algebras associated with a quasitriangular Hopf algebraH. We show that these two types of algebras are twist-equivalent. It follows that a RE algebra is a module algebra over a twisted
tensor square ofH. We present some applications to the equivariant quantization.
