Log intersection theory of the moduli space of curves


Abstract
             

The logarithmic intersection theory of the moduli space of curves is defined via a limit over all log blow-ups (with respect to the normal crossings boundary structure). I will explain some new results and directions related to the log cohomology theory and the log double ramification cycle. Joint work with D. Holmes, S. Mocho, A. Pixton, and J. Schmitt.
