局部和非局部乘法Poisson顶点代数与微分差分方程

Local and non-local multiplicative Poisson vertex algebras and differential-difference equations

Alberto De Sole, Victor G. Kac, Daniele Valeri, Minoru Wakimoto

摘要:

我们发展的乘法李共形和泊松顶点代数,本地和非本地的概念,以及它们的连接到可积微分差分哈密顿方程的理论。我们建立了这些概念与$q$ -变形$W$ -代数和格Poisson代数的关系。引入Adler型伪差分算子的概念,并将其应用于微分差分Hamilton方程的可积性。

英文摘要:

We develop the notions of multiplicative Lie conformal and Poisson vertex algebras, local and non-local, and their connections to the theory of integrable differential-difference Hamiltonian equations. We establish relations of these notions to $q$-deformed $W$-algebras and lattice Poisson algebras. We introduce the notion of Adler type pseudodifference operators and apply them to integrability of differential-difference Hamiltonian equations.
