Tensor Finite Element Methods for the Spectral Fractional Laplacian

In this talk we discuss the analysis and fast implementation of numerical algorithms for the solution of fractional linear elliptic problems on a bounded domain with a homogeneous Dirichlet boundary c...

Flagellar swimming and amoeboid motion in Euglena gracilis: the how and why of a behavioral change in a unicellular organism

Abstract: Euglena gracilis is a unicellular protist exhibiting different motility strategies: swimming by flagellar propulsion, or crawling thanks to large amplitude shape changes of the whole body (a...

Modelling reaction-diffusion beyond the Fourier law

The classical modelling of diffusion processes posits that the flux is proportional to the gradient of the density, with the final output that the resulting equation is parabolic. Such description has...

Scattering from local deformations of a semitransparent plane

Abstract: I will discuss the scattering problem for a quantum particle in dimension three in the presence of a semitransparent unbounded obstacle, modeled by a surface. The generator of the dynamics i...

Chorin’s approaches revisited: Particle Vortex Method vs Finite Volume Method

In this work a Vortex Particle Method is combined with a Boundary Element Method for the study of viscous incompressible planar flow around solid bodies. The method is based on Chorin’s operator split...

Social learning leads to the recurrence of corruption

Abstract: Cooperation can be sustained by institutions that punish free-riders. Such institutions, however, tend to be subverted by corruption if they are not closely watched. Monitoring can uphold a ...

Numerical methods for compressible Navier-Stokes equations

We review numerical methods for direct numerical simulation of turbulent compressible flow in the presence of shock waves. Ideal numerical methods should be accurate and free from numerical dissipatio...

On Gibbs-Shannon Entropy

This talk will focus on the question of the physical contents of the Gibbs-Shannon entropy outside equilibrium. It will be based on the article Gavrilov-Chetrite-Bechhoeffer, Direct measurement of wea...

Minimizzazione di funzionali energia attraverso un’adattazione anisotropa della mesh

In questa presentazione ci focalizziamo su due diversi tipi di fenomeni che possono essere modellati attraverso la minimizzazione di un opportuno funzionale energia, ovvero la propagazione di fratture...
