On the deformation of /Λ-symmetry in B-field background
Abstract
In this note we will show that the /Λ 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.
