Poisson sigma models on surfaces with boundary: classical and quantum aspects
Ivan Calvo
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…
Dual branes in topological sigma models over Lie groups. BF-theory and non-factorizable Lie bialgebras
Ivan Calvo, Fernando Falceto
We complete the study of the Poisson-Sigma model over Poisson-Lie groups. Firstly, we solve the models with targets and (the dual group of the Poisson-Lie group ) corr…
Supersymmetric WZ-Poisson sigma model and twisted generalized complex geometry
Ivan Calvo
It has been shown recently that extended supersymmetry in twisted first-order sigma models is related to twisted generalized complex geometry in the target. In the general case the…
Star products and branes in Poisson-Sigma models
Ivan Calvo, Fernando Falceto
We prove that non-coisotropic branes in the Poisson-Sigma model are allowed at the quantum level. When the brane is defined by second-class constraints, the perturbative quantizati…
Poisson-Dirac branes in Poisson-Sigma models
Ivan Calvo, Fernando Falceto
We analyse the general boundary conditions (branes) consistent with the Poisson-sigma model and study the structure of the phase space of the model defined on the strip with these…
Poisson reduction and branes in Poisson-Sigma models
Ivan Calvo, Fernando Falceto
We analyse the problem of boundary conditions for the Poisson-Sigma model and extend previous results showing that non-coisotropic branes are allowed. We discuss the canonical redu…
