In 1961 Rees proved a criterion for integral dependence between two ideals of finite colengths by the equality of their…

Some estimates in (fractional) spectral geometry – Lorenzo Brasco (Università di Ferrara)
We consider the first eigenvalue of the Dirichlet-Laplacian in a general open set. We seek for a geometric lower bounds,…
Finiteness properties, subgroups of hyperbolic groups and complex hyperbolic lattices – Claudio Llosa Isenrich (Karlsruhe Institute of Technology)
Hyperbolic groups form an important class of finitely generated groups that has attracted much attention in Geometric Group Theory. We call…
Travelling waves for a nonlinear Schrödinger system with quadratic interaction – Masayuki Hayashi (Università di Pisa)
Solitary waves (solitons, standing waves, traveling waves) are known to play a fundamental role in the analysis of nonlinear dispersive…
Un recente modello matematico di percezione del colore basato sull’informazione quantistica – Edoardo Provenzi (Université de Bordeaux)
La percezione del colore da parte del sistema visivo umano è un fenomeno complesso e affascinante che è stato studiato da molti fisici e matematici di prima importanza, tra cui Newton, Maxwell, Grassmann e Helmholtz, per citare solo i più noti. Nel…
Optimal Quantization and Centroidal Voronoi Tessellations – Rustum Choksi (McGill University)
Nonconvex and nonlocal variational problems are pervasive in energy-driven pattern formation.Two central issues are: (Q1) can one conjecture and prove…
The quest for a functional equation of L-functions in Drinfeld theory – Giacomo Hermes Ferraro (Sapienza Università di Roma)
The theory of Drinfeld modules, pioneered by Anderson and Thakur in the 90’s, was conceived as a possible analogue to…
No blow-up by nonlinear Ito noise for Euler equations – Marco Bagnara (Scuola Normale Superiore)
We consider the 2D and 3D stochastic Euler equations. It is well-known that (under suitable assumptions on the noise) regular…
Combinatorial statements from a compact right topological semigroup of types – Claudio Agostini (TU Wien)
Many theorems in combinatorics share a very similar structure: Let $M$ be monoid acting by endomorphism on a partial semigroup $S$. For each finite coloring of $S$, there are “nice” monochromatic subsets $N\subseteq S$. Examples of theorems of…
Integral Simplicial Volume and Delta Complexity: find the differences – Federica Bertolotti (SNS Pisa)
Integral Simplicial Volume and Delta Complexity are invariants that try to capture the complexity of manifolds in terms of simplices…
