Double ramification cycles and integrable hierarchies
Published 7 Mar 2014 in math-ph, math.AG, and math.MP | (1403.1719v3)
Abstract: It this paper we present a new construction of a hamiltonian hierarchy associated to a cohomological field theory. We conjecture that in the semisimple case our hierarchy is related to the Dubrovin-Zhang hierarchy by a Miura transformation and check it in several examples.
