Les Houches lecture notes on moduli spaces of Riemann surfaces

open access: yesSciPost Physics Lecture Notes
In these lecture notes, we provide an introduction to the moduli space of Riemann surfaces, a fundamental concept in the theories of 2D quantum gravity, topological string theory, and matrix models. We begin by reviewing some basic results concerning the

Quantum Dynamics on the Worldvolume from Classical su(n) Cohomology

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
A key symmetry of classical p-branes is invariance under worldvolume diffeomorphisms. Under the assumption that the worldvolume, at fixed values of the time, is a compact, quantisable Kähler manifold, we prove that the Lie algebra of volume-preserving ...

Semisimple Quantum Cohomology and Blow-ups

open access: yes, 2004
Using results of Gathmann, we prove the following theorem: If a smooth projective variety X has generically semisimple (p,p)-quantum cohomology, then the same is true for the blow-up of X at any number of points. This a successful test for a modified version of Dubrovin's conjecture from the ICM 1998.
