Bihamiltonian structure of the $(n, 1)$ -type rational reductions of the 2D-Toda hierarchy

Haonan Qu, Qiulan Zhao

We derive a local bihamiltonian structure for the rational reduction of the 2D-Toda hierarchy (RR2T) of $(n, 1)$ -type by direct computations, and construct an $(n + 1)$ -dimensional se…

Asymmetric rational reductions of 2D-Toda hierarchy and a generalized Frobenius manifold

Haonan Qu, Qiulan Zhao

We study the local bihamiltonian structures of the asymmetric rational reductions of the 2D-Toda hierarchy (RR2T) of types $(2, 1)$ and $(1, 2)$ at the full-dispersive level, and con…
