Domino tilings of the Aztec diamond in random environment

Panagiotis Zografos

Abstract:
The Aztec diamond, under the uniform measure on domino tilings, is one of the classical gems
of integrable probability. Its special structure makes it exactly solvable, and over the years...

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...

A Pre-tty Pre-amble to Pre-Lie Algebras from Combinatorial Species

Yannic Vargas (CUNEF University Madrid)

We present an introduction to pre-Lie algebras, an algebraic structure closely related to Lie algebras. From a combinatorial perspective, pre-Lie algebras are connected to the notion of insertion of...

On local boundary conditions for Dirac-type operators

Nadine Große (Freiburg)

We discuss smooth local boundary conditions for Dirac-type operators, giving existence and non-existence results for local self-adjoint boundary conditions and discuss concrete parametrizations of the...
