Algebraic curves and surfaces : a history of shapes / Laurent Busé, Fabrizio Catanese, Elisa Postinghel.

This volume collects the lecture notes of the school TiME2019 (Treasures in Mathematical Encounters). The aim of this book is manifold, it intends to overview the wide topic of algebraic curves and surfaces (also with a view to higher dimensional varieties) from different aspects: the historical dev...
