Linearly Degenerate Hamiltonian PDEs and a New Class of Solutions to the WDVV Associativity Equations

B. A. Dubrovin, M. V. Pavlov, S. A. Zykov

We define a new class of solutions to the WDVV associativity equations. This class is determined by the property that one of the commuting PDEs associated with such a WDVV solution…
