14 Dec 2011 | | Abstract: | Branes and defects in topological Landau-Ginzburg models are described by
matrix factorisations. We revisit the problem of deforming them and discuss
various deformation methods as well as their relations. We have implemented
these algorithms and apply them to several examples. Apart from explicit
results in concrete cases, this leads to a novel way to generate new matrix
factorisations via nilpotent substitutions, and to criteria whether boundary
obstructions can be lifted by bulk deformations. | | Source: | arXiv, 1112.3352 | | Services: | Forum | Review | PDF | Favorites | |
