Ricci flow from spaces with conical singularities

Lucas Lavoyer (Münster)

In the first part of this talk, we will discuss some results on smoothing properties of the Ricci flow. In particular, we will consider the Ricci flow out of spaces with edge type conical...

Hodge Dualities in the Perturbation Setup and Applications:Perturbed Zeta Determinant and Analytic Torsion

Ihsane Malass

We consider the perturbation of the exterior differential by a closed one-form \(a\), \(d_a := d + a \wedge \cdot\), on a manifold with boundary. This gives rise to the perturbed (or twisted) de Rham...

Equivalence between local and global Hadamard States with Robin boundary conditions on half-Minkowski spacetime

Claudio Dappiaggi (Pavia)

We construct the fundamental solutions and Hadamard states for a Klein-Gordon field in half-Minkowski spacetime with Robin boundary conditions in arbitrary dimensions using a generalisation of the...
