Poisson sigma models on surfaces with boundary: classical and quantum aspects

The topics covered in this thesis may be divided into three parts. Firstly, we perform a study on the most general branes which are consistent with the Poisson sigma model, both at the classical and quantum levels. The second part is devoted to the particular case in which the target Poisson manifold is a Poisson-Lie group. Finally, we investigate the supersymmetric version of the twisted Poisson sigma model and its connection with twisted generalized complex geometry.
