Prossimi seminari del Dipartimento di Matematica

nel ciclo di seminari: SEMINARIO DI ALGEBRA E GEOMETRIA

ore 12:00

presso - Aula Da Stabilire -

algebra e geometria

A classical result due to Clebsch from the mid-nineteenth century confirms that every complex space sextic curve (given as an intersection of a quadric and a cubic surface in projective 3-space) has exactly 120 tritangent planes. In this talk we will show how to use combinatorial methods arising from tropical geometry to revisit this classical problem and perform the analogous count over the reals and extensions thereof. This is joint work with Yoav Len, Hannah Markwig and Yue Ren (arXiv:2512.24277 and arXiv:2605.19905).

On a Fractional Lin–Ni-Takagi Type Problem with Spectral Neumann Boundary Conditions

nell'ambito della serie: SEMINARI DI ANALISI MATEMATICA BRUNO PINI

ore 16:00

presso Aula Cremona

seminario on line • collegamento al meeting

analisi matematica

In this seminar, we will discuss a fractional version of a semilinear Neumann problem originally studied by Lin, Ni, and Takagi in the late 1980s. This problem arises when considering the steady states of the Keller–Segel model with nonlocal diffusion of the chemical concentration. Following the approach of Stinga and Volzone, we will consider the system equipped with spectral Neumann boundary conditions. We will investigate the existence of non-constant least-energy solutions and show that, provided the diffusion parameter is small enough, these solutions attain their global maximum at exactly one point on the boundary. Furthermore, we will prove that if the diffusion parameter is sufficiently large, any solution to the system must necessarily be constant. Based on ongoing project with Eleonora Cinti (UNIBO), Marco Ghimenti (UNIPI), and Jun-cheng Wei (CUHK).

Conference

ASK 2026 Conference in Geometric Analysis and PDEs

da mercoledì 02 settembre 2026 a venerdì 04 settembre 2026

The goal of the ASK 2026 - Geometric analysis and PDE conference is to bring together young researchers from various fields of Mathematical Analysis, specifically the geometric analysis of Partial Differential Equations (PDEs), linear and nonlinear PDEs, dispersive PDEs, microlocal analysis, regularity theory of PDE solutions, as well as the calculus of variations. The interdisciplinary nature of the event aims to foster interaction and collaboration among mathematicians specializing in the aforementioned fields, through invited talks by researchers from Italian and international universities, and through contributions from young scholars. Finally, to encourage networking, the schedule includes dedicated time for both formal and informal discussions. For over two years, the ASK group has been organizing periodic seminars and previously hosted another conference in December 2024.
