Formation of Singularities in the MCF

IMAG

The Mean Curvature Flow (MCF) describes the evolution of hypersurfaces in Euclidean space, driven by their mean curvature, which tends to smooth out geometric irregularities over time. However, singularities inevitably develop during the flow, marking critical points where the smooth evolution ceases. In this talk, we will examine the formation of singularities in MCF, focusing on the crucial role of tangent flows in their analysis. Tangent flows, which emerge as blow-up limits near singularities, often exhibit self-similar structures. We will highlight how the mean curvature flow produces a specific type of tangent flow at the first singularity, preserving notable geometric and topological properties of the compact initial data. This presentation is based on an ongoing work with David Hoffman and Brian White.

On the existence and classification of k-Yamabe gradient solitons

Pontificia Universidad Católica de Chile

The k-Yamabe problem is a fully non-linear extension of the classical Yamabe problem that seeks for metrics of constant k-curvature. In this talk I will discuss this equation from the point of view of geometric flows and provide existence and classification results on soliton solutions for the k-Yamabe flow. This is joint work with Maria Fernanda Espinal

Eigenvalue estimates on shrinkers

Columbia University

We discuss an eigenvalue estimate that holds on every embedded self-similar shrinker for mean curvature flow. This result is obtained via a Reilly-type formula and can be viewed as an analogue of the first eigenvalue estimate obtained by Choi and Wang for embedded minimal hypersurfaces in the round sphere. Our estimate generalizes earlier work of Ding and Xin on closed self-shrinkers by introducing and minimizing a new functional to treat the non-compact case. This is joint work with Simon Brendle.

VII Congreso de Jóvenes Investigadores de la RSME

Bilbao (Spain)

» 
El Congreso de Jóvenes Investigadores de la Real Sociedad Matemática Española (RSME) es un congreso bianual de la RSME donde investigadores jóvenes de todo el mundo con vinculación a la comunidad matemática española se encuentra para compartir sus últimos resultados de investigación, pero sobretodo para crear nuevos lazos y seguir tejiendo redes de colaboración entre quienes formarán la futura comunidad matemática. Tras sus seis ediciones previas en Soria (2011), Sevilla (2013), Murcia (2015), Valencia (2017), Castellón (2020) y León (2023), la séptima edición tendrá lugar en la villa de Bilbao del 13 al 17 de enero del 2025 siendo la Universidad del País Vasco/Euskal Herriko Univertsitatea (UPV/EHU) la institución anfitriona y organizadora y el Basque Center for Applied Mathematics (BCAM) co-organizador.
