摘要：Curve-counting theories developed over the last two decades are built upon intersection theory on moduli stacks. For quasi-smooth moduli stacks, virtual fundamental classes and virtual structure sheaves are fundamental objects, and the virtual pullbacks formalism provides a unifying framework to understand their properties. In this talk, I will first review relevant background and motivation, then sketch this formalism and its application to K-theoretic curve-counting theories.
