Title: Counting curves - logarithmic double ramification cycle (MI talk)
Speaker: Pim Spelier
How many circles are tangent to three given circles in the plane? These kinds of questions are part of enumerative geometry, a branch of algebraic geometry concerned with counting objects. In this talk I will give a gentle introduction to the subject of counting curves, introducing some of the tools like moduli spaces and intersection theory. In the last part I will talk about my own work on logarithmic Gromov-Witten invariants and the logarithmic double ramification cycle, special kind of curve counts involving tangency constraints.
