Perturbative and Non-perturbative Approaches to String Sigma-Models in AdS/CFT

Nominated as an outstanding Ph.D. thesis by the Humboldt University Berlin, Berlin,Germany Provides a clear introduction to the superstring models relevant for the N=4 super Yang-Mills (N=4 SYM) and ABJM theory, complemented by appendices and references for further reading

Offers pedagogical explanations of typical string perturbative calculations at one- (functional determinants) and two loops (Feynman diagrams)

Presents an innovative approach to 2d worldsheet theory via lattice field theory
