Title: Comparison Formulae for Donaldson-Thomas Invariants
Abstract: Donaldson-Thomas numbers are virtual enumerative invariants attached to Calabi-Yau threefolds. I will begin the talk to provide some intuition for these, in the context of curve-counting. I will then discuss a few comparison formulae.
