T-dualization of bosonic string and type II superstring in presence of coordinate dependent background fields


Abstract: In this talk we will discuss one of the ways how coordinate noncomutativity arises in the context of string theory. Starting point of the talk will be a short introduction to string theory, where we will discuss basic formalism for both bosonic string and supersymmetric string, we will also discuss dualities that are present in the theory. After this, discussion will focus on procedure for obtain in T-dual theories. This procedure will be applied first on bosonic string and later on superstring, where, after obtaining T-dual theories, we will discuss what effect did T-duality have on structure of Poisson brackets.
