Catalan percolation

In Catalan percolation, one declares the edges {i,i+1}, for integer i, occupied and each edge {i,j} with j> i+1 open independently with probability p. For k> i+1, we recursively define {i,k} to ...

Entropy solutions of scalar nonlocal conservation laws with congestion

In this talk we consider a class of scalar nonlinear models describing crowd dynamics. The congestion term appears in the transport equation in the form of a compactly supported nonlinear mobility fun...

A Harnack type inequality for singular Liouville type equations

We are concerned with a generalization to the singular case of a result of C.C. Chen e C.S. Lin [Comm. An. Geom. 1998] for Liouville-type equations with rough potentials. The singular problem is actua...

Quiver presentations for KLR algebras and Hecke categories

The ultimate goal of representation theory is to obtain a complete understanding of the submodule structure of some algebraic objects. In this talk we will tackle this problem for KLR algebras. In par...

Quantum reference frames and operator algebras

In this talk I will present the recent paper by Fewster, Janssen, Loveridge, Waldron and myself: "Quantum reference frames, measurement schemes and the type of local algebras in quantum field theory."...

Infinitesimal Torelli and rigidity results for a remarkable class of elliptic surfaces

I will discuss joint work with Chris Peters which extends rigidity results of Arakalov, Faltings and Peters to period maps arising from families of complex algebraic varieties which are non-necessaril...

Modular resolutions of moduli of stable maps and reduced invariants

Gromov-Witten invariants are defined via intersection theory on Kontsevich's space of stable maps. The latter is very singular, with many irreducible components of different dimensions. As a consequen...

Symplectic duality and the Hikita-Nakajima conjecture

We will discuss the general notion of symplectic duality (also known as 3D mirror symmetry) between symplectic resolutions of singularities. We will give examples of dual varieties such as Higgs and C...

Alternative Modular Compactifications of M_{g,n} via Cluster Algebras with applications to the MMP of \overline{M}_{g,n}

We will discuss modular compactifications of M_{g,n} (the moduli space of smooth curves) and their birational geometry within the framework of the Hassett-Keel program. We classify the open substacks ...

Plane curves and logarithmic vector fields

I will discuss some questions on plane curves which involve logarithmic vector fields and provide a new viewpoint on classical problems and results....
