On $W_{1+\infty }$ $n$-algebra

Abstract

We present the nontrivial $W_{1+\infty }$ $n$-algebra and analyze its remarkable properties. We investigate the $W_{1+\infty }$ $n$-algebra in the Landau problem and discuss the realization of the classical $w_{\infty }$ 3-algebra. Furthermore, we discuss the case of the many-body system in the lowest Landau level and derive the constraints for correlation functions of the vertex operators.
