Abstract

In the present thesis, we explore certain aspects of superstring and supersymmetric gauge ﬁeld theory, independently as well as in the context of the holographic duality.The ﬁrst part of the thesis is devoted to classical integrability and, in particular, to certain methods of analytic non-integrabi...
