Principal hierarchy of Infinite-dimensional Frobenius Manifold Underlying the Extended Kadomtsev-Petviashvili Hierarchy (2309.10389v1)
Published 19 Sep 2023 in math-ph, math.MP, and nlin.SI
Abstract: In this paper, we construct the principal hierarchy of the infinite-dimensional Frobenius manifold underlying the extended Kadomtsev-Petviashvili hierarchy. We show that this hierarchy serves as an extension of the genus zero Whitham hierarchy with one movable pole.
