The geometry of the moduli space of curves
Interactive overview of what is known about the geometry of the moduli spaces of stable n-pointed genus-g curves and their interiors.
An interactive table recording known geometric invariants of the moduli spaces of stable n-pointed genus-g curves and of their interiors, the moduli of smooth pointed curves: the Kodaira dimension, whether the Chow ring is generated by tautological classes, and whether point counts over finite fields are polynomial, with each cell giving the value together with references.
