Rigid, Not Infinitesimally Rigid Surfaces of General Type with Ample Canonical Bundle

Explore a cutting-edge lecture on the construction of surfaces of general type with ample canonical bundle and unique properties in their Kuranishi and Gieseker moduli spaces. Delve into ongoing research by Christian Böhning, Roberto Pignatelli, and Hans-Christian von Bothmer as they utilize configurations of lines, incidence schemes, and abelian cover theory to create surfaces with non-reduced point Kuranishi spaces. Gain insights into how nearly rational varieties contribute to this construction and discover the intriguing aspects of this specialized topic in algebraic geometry. Despite its thematic divergence from the main conference subject, engage with this fun and intellectually stimulating presentation delivered by Christian Böhning from the University of Warwick.
