TL;DR

This paper explores the infinite dimensional W-geometry of a second quantized free string, integrating W-symmetries into the geometric framework of quantum string field theory through algebraic transformations.

Contribution

It introduces a method to incorporate W-symmetries into the infinite dimensional geometric structure of quantum string theory by transforming the underlying Lie algebra.

Findings

W-symmetries are integrated into the geometric framework of string theory.

A method to derive W-algebras from classical W-transformations is proposed.

Connections to nonlinear Poisson brackets and nonlinear geometric algebra are discussed.

Abstract

The present paper is devoted to various objects of the infinite dimensional W-geometry of a second quantized free string. Our purpose is to include the W-symmetries into the general infinite dimensional geometrical picture related to the quantum field theory of strings, which was described in the first part of the paper (Algebras Groups Geom.11(1994)[to appear]). It is done by the change of the Lie algebra of all infinitesimal reparametrizations of a string world-sheet on the Lie quasi(pseudo)algebra of classical W-transformations (Gervais-Matsuo quasi(pseudo)algebra) as well as of the Virasoro algebra on the central extended enlarged Gervais-Matsuo quasi(pseudo)algebra. A way to obtain W-algebras from classical W-transformations (i.e. Gervais-Matsuo quasi (pseudo)algebra) is proposed. The relation of Gervais-Matsuo differential W-geometry to the Batalin-Weinstein-Karasev-Maslov approach to nonlinear Poisson brackets as well as to L.V.Sabinin program of "nonlinear geometric algebra" are mentioned.
