Abstract
摘要 |
We explain basic ideas of homological methods in quantum field theory via the Batalin-Vilkovisky formalism. We illustrate its applications by two examples: 1. A formulation of QFT bundle as the geometry of localized effective theory and Index theory; 2. Anomaly cancellation in open-closed topological string field theory via large N homological method. The talk is based on two works: arXiv 1911.11173[Math.QA] and arXiv 1905.09269[hep-th]. |
