| Two-Dimensional Ultra-Toda Integrable Mappings and Chains (Abelian Case) | ||
| Protvino, 1997.- p.16, refs.:12. | ||
A new class of integrable mappings and chains is introduced. Corresponding (1+2) integrable systems invariant with respect to such discrete transformations are represented in an explicit form. Soliton like solutions of them are represented in terms of matrix elements of fundamental representations of semisimple $A_n$ algebras for the given group element.
