KurzbeschreibungClassical algebraic geometry, taught in graduate-level courses, is only a shadow of the complete framework offered by derived algebraic geometry. I will describe the new insights and applications that are offered by the latter while avoiding being as technical as the standard literature cited below.
LernzielA keen listener should understand by the end of the course why derived algebraic geometry is useful and have an idea of where to begin in applying it to problems in enumerative questions.
InhaltStarting from the primary building blocks called cdga's, I will first develop some intuition behind derived algebraic geometry by explaining the hidden smoothness phenomenon - the main benefit of working with derived algebraic geometry. Moving on to the global picture, I will motivate the definition of derived stacks, and shifted symplectic structures while describing their natural origin coming from Calabi-Yau categories. I will end by discussing dg-quivers and their moduli stacks of dg-representations as a natural source of examples.

Voraussetzungen / BesonderesOne should have a good understanding of algebraic geometry, algebraic topology and category theory.

Familiarity with some enumerative geometry using virtual fundamental classes would be helpful for understanding the goal of the course but is not required.

KurzbeschreibungThe main goal is to introduce this subject to a wider audience in a more intuitive way. The course should ideally end with applications of derived algebraic geometry to constructing virtual fundamental classes in enumerative geometry using perverse sheaves.
LernzielA keen listener should understand by the end of the course why derived algebraic geometry is useful and have an idea of where to begin in applying it to problems in enumerative geometry.
