Title. Multiplicative Poisson vertex algebras and differential-difference Hamiltonian equations
Abstract. It has been demonstrated in the past few years that Poisson
vertex algebras (quasiclassical limits of vertex=chiral algebras) is the
adequate framework for the theory of Hamiltonian PDE.
After explaining this, I will demonstrate that likewise the multiplicative
Poisson vertex algebras is the adequate framework for the theory of
Hamiltonian differential-difference equations.
