Infinite-dimensional Frobenius Manifolds Underlying the Toda Lattice Hierarchy (1305.1030v2)
Published 5 May 2013 in math-ph, math.DG, and math.MP
Abstract: Following the approach of Carlet et al.(2011)\cite{CDM}, we construct a class of infinite-dimensional Frobenius manifolds underlying the Toda lattice hierarchy, which are defined on the space of pairs of meromorphic functions with possibly higher-order poles at the origin and at infinity. We also show a connection between these infinite-dimensional Frobenius manifolds and the finite-dimensional Frobenius manifolds on the orbit space of extended affine Weyl groups of type $A$ defined by Dubrovin and Zhang.
