Numerical simulation of wave propagation from deep waters to very shallow waters, including changes over real bottoms

On the regularity of the vanishing ideals of graphs
Speaker: Jorge Neves (CMUC, Univ. Coimbra)
In 2011, Renteria, Simis and Villarreal introduced a new class of binomial ideals associated to graphs. One associates to a simple graph, G, the vanishing ideal of a subset of a projective space over a finite field, parameterized by the edges of the graph. Although originally these ideals were...
A tour in extreme value laws
Speaker: Jorge Soares (UC|UP PhD student)
In this talk, we analyse the stochastic process that arises from a dynamical system by evaluating an observable function along a given orbit of the system. Our goal is to give sufficient conditions for the existence of an Extreme Value Law for the considered process. We will present an example where...
Product formulas, generalized convolutions and integral transforms
Speaker: Rúben Sousa (UC|UP PhD student)
It is well-known that the ordinary convolution is closely related with the Fourier transform. It is therefore natural to ask: for other important integral transforms, can we define generalized convolution operators having analogous properties? Actually, the answer depends on the existence of a...
Phaseless rank and amoebas
Speaker: António Goucha (UC|UP PhD student)
The phaseless rank of a nonnegative matrix M is defined to be the least k for which there exists a complex matrix N such that |N| = M, entrywise speaking. In optimization terms, it is the solution to the rank minimization of a matrix under phase uncertainty on the entries. This concept has a strong...
Price models in mean-field games

Diogo Gomes (KAUST, Saudi Arabia)

In this talk, we introduce a price-formation model for electricity markets where a large number of small players can store and trade electricity. Our model is a constrained mean-field game (MFG) where the price is a  Lagrange multiplier for the supply vs. demand balance condition. Under mild...
Entropy numbers of compact embeddings or radial and multi-radial subspaces of Sobolev spaces with applications.
