Integrable Mappings Related to the Extended Discrete KP Hierarchy
A. K. Svinin
We investigate self-similar solutions of the extended discrete KP hierarchy. It is shown that corresponding ansatzes lead to purely discrete equations with dependence on some numbe…

We exhibit the dispersionless limit of the extended discrete KP hierarchy.

Invariant Submanifolds of Darboux-KP Chain and Extension of the Discete KP Hierarchy
A. K. Svinin
Invariant submanifolds of the so-called Darboux-KP chain are investigated. It is shown that restriction of dynamics on some class of invariant submanifolds yields the extension of…
