On the Deformation of $\Lambda$-Symmetry in B-field Background

Abstract

In this note we will show that the $\Lambda$ symmetry, namely the U(1) symmetry of the open string sigma model which relates the B-field and the U(1) gauge field of a brane to each other, is deformed to a noncommutative version in a constant B-field background.
