On growth and instability for semilinear evolution equations: an abstract approach
for semilinear abstract evolution equations with compact nonlinearities. We show, in particular, that compact nonlinear perturbations of linear evolution equations can exponential lower bounds of solutions for ini...

The complete set of generalized symmetries for the Calogero-Degasperis-Ibragimov-Shabat equation
We find the complete set of local generalized symmetries (including x, t-dependent ones) for the Calogero-Degasperis-Ibragimov-Shabat equation, and investigate the properties of these symmetries....

Non-Hermitian interaction representation and its use in relativistic quantum mechanics
The textbook interaction-picture formulation of quantum mechanics is extended to cover the unitarily evolving systems in which the Hermiticity of the observables is guaranteed via an ad hoc amendment of the inner product in Hilbert space. These syste...

Unification in varieties of completely simple semigroups
We consider solvability of equations with constants in varieties VCS of all completely simple semigroups with subgroups in a given variety V of groups. An equation systemof m^{2n} equations is solvable in V. Moreov...

A remark on nonlocal symmetries for the Calogero--Degasperis--Ibragimov--Shabat equation
We consider the Calogero-Degasperis-Ibragimov-Shabat (CDIS) equation and find the complete set of its nonlocal symmetries depending on the local variables and on the integral of the only local conserved density of the e...

Ensemble approximations for constrained dynamical systems using Liouville equation
For a class of state-constrained dynamical systems described by evolution variational inequalities, we study the time evolution of a probability measure which describes the distribution of the state over a set. In contrast ...

System of fuzzy relation equations with inf-> composition: complete set of solutions
The problem of solvability of a system of equations with infr composition has been considered in semilinear spaces. We used the fact that a set of solutions is determined by maximal solutions and therefore, we focused on characteriz...
