-universal Hopf algebras (co)acting on -algebras
Ana Agore, Alexey Gordienko, Joost Vercruysse
We develop a theory which unifies the universal (co)acting bi/Hopf algebras as studied by Sweedler, Manin and Tambara with the recently introduced \cite{AGV1} bi/Hopf-algebras that…
Equivalences of (co)module algebra structures over Hopf algebras
Ana Agore, Alexey Gordienko, Joost Vercruysse
We introduce the notion of support equivalence for (co)module algebras (over Hopf algebras), which generalizes in a natural way (weak) equivalence of gradings. We show that for eac…
Categories and weak equivalences of graded algebras
Alexey Gordienko, Ofir Schnabel
When one studies the structure (e.g. graded ideals, graded subspaces, radicals, ...) or graded polynomial identities of graded algebras, the grading group itself does not play an i…
Modelling Solutions to the Kdv-Burgers Equation in the Case of Non-homogeneous Dissipative Media
Alexey Samokhin
We study the behavior of the soliton which, while moving in non-dissipative medium encounters a barrier with finite dissipation. The modelling included the case of a finite dissipa…
Contact Integrable Extensions of Symmetry Pseudo-Group and Coverings of the r-th Modified Dispersionless Kadomtsev -- Petviashvili Equation
Oleg I. Morozov
We apply the technique of integrable extensions to the symmetry pseudo-group of the r-th mdKP equation. This gives another look on deriving known coverings and allows us to find ne…
Cartan's structure of symmetry pseudo-group and coverings for the r-th modified dispersionless Kadomtsev--Petviashvili equation
Oleg I. Morozov
We derive two non-equivalent coverings for the r-th mdKP equation from Maurer--Cartan forms of its symmetry pseudo-group. Also we find Bäcklund transformations between the covering…
