78. Alex Takeda : Pre-Calabi-Yau structures on the categorical formal neighborhood of infinity and the string coproduct

Pre-Calabi-Yau structures are noncommutative versions of Poisson structures, which exist on many dg/A-infinity categories of interest in mirror symmetry. In this talk, I will explain a relation between these structures and Efimov's notion of the "categorical formal punctured neighborhood of infinity", which generalizes the category of perfect complexes near the divisor at infinity in a...
