Title: On geography of log Calabi-Yau

Date: Dec 6, 2017

Place: University of Georgia, Athens

Abstract:
I will discuss some problems and questions on geography of log Calabi-Yau such as proper Calabi-Yau or Fano manifolds. I will introduce polar dg-ring such that to every log CY one associates an element of that ring, proper CY produce closed elements. An interesting question is to demonstrate that some CY gives non-exact element.
