Domain variations and applications to elliptic problems with Robin boundary conditions
In the calculus of variations symmetrization techniques are useful for estimating the energy or the Rayleigh quotient provided the solutions of the underlying problems satisfy a Dirichlet boundary condition. The ball is then the optimal domain. In the case of Robin boundary conditions symmetrization is not applicable in general, and the question whether or not the ball is optimal is not clear. Partial answers can be obtained by means of domain variations. This talk is based on a study in collaboration with Alfred Wagner.

Thomae formulas for general Abelian covers of CP1
100 years and a change: Thomae designed a formula calculating certain value of theta functions as polynomial up to a constant. I will explain the generalization of these formulas for General Abelian Covers.

On the Taylor expansion of lambda-terms and the groupoid structure of their approximants
We show that the normal form of the Taylor expansion of a lambda-term is isomorphic to its Bohm tree, improving Ehrhard and Regnier's original proof along three independent directions. First, we simplify the final step of the proof by following the left reduction strategy directly in the resource calculus, avoiding to introduce an abstract machine ad-hoc. We also introduce a groupoid of permutations of copies of arguments in a rigid variant of the resource calculus, and relate the coefficients of Taylor expansion with this structure, while Ehrhard and Regnier worked with groups of permutations of occurrences of variables. Finally, we extend all the results to a non-deterministic setting: by contrast with previous attempts, we show that the uniformity property that was crucial in Ehrhard and Regnier's approach can be preserved in this setting.
