Résumé : For a given measure we construct a random measure on the Brownian path that has expectation the given measure. For the construction we use the concept of weak convergence of random measures in probability. The machinery can be extended to more general sets than Brownian path. The ideas and results have the ease of Kahane’s T-martingales but in the case of Brownian path it is not a T-martingale.

Symplectic resolutions of quiver varieties

Résumé : Quiver varieties, as introduced by Nakaijma, play a key role in representation theory. They give a very large class of symplectic singularities and, in many cases, their symplectic resolutions too. However, there seems to be no general criterion in the literature for when a quiver variety admits a symplectic resolution. In this talk I will give necessary and sufficient conditions for a quiver variety to admit a symplectic resolution. This result builds upon work of Crawley-Boevey and of Kaledin, Lehn and Sorger. The talk is based on joint work with T. Schedler.
