Symmetry Flows, Conservation Laws and Dressing Approach to the Integrable Models
H. Aratyn, J. F. Gomes, E. Nissimov +2
The graded affine Lie algebras provide a framework in which the dressing method is applied to the generic type of integrable models. The dressing formalism is used to develop a uni…

Gauging of Geometric Actions and Integrable Hierarchies of KP Type
Emil Nissimov, Svetlana Pacheva
This work consist of two interrelated parts. First, we derive massive gauge-invariant generalizations of geometric actions on coadjoint orbits of arbitrary (infinite-dimensional) g…

Loop-Algebra and Virasoro Symmetries of Integrable Hierarchies of KP Type
H. Aratyn, J. F. Gomes, E. Nissimov +1
We propose a systematic treatment of symmetries of KP integrable systems, including constrained (reduced) KP models ${\sl cKP}_{R,M}$, and their multi-component (matrix) generaliza…
