Beijing-Novosibirsk seminar on geometry and mathematical physics——Exponential Networks and enumerative invariants of local CY

2020-11-26 17:00 online

Abstract:
Exponential networks (EN) are a variant of the spectral networks of Gaiotto-Moore-Neitzke, for the case of logarithmic differentials and they naturally lead to Donaldson-Thomas type invariants of local CY 3-folds. I will define ENs and subsequently describe how to get the invariants, illustrated by some examples. If time permits I will show some recent development for cases with compact 4-cycles.
