[Insalate Di Matematica]

Dear all,

For the *next appointment* of the series of seminars "Insalate di
Matematica", *Gaia Bombardieri* (University of Padova) will give a talk.
The speaker will deliver the talk *in presence* and the meeting will also
be broadcasted *online* (see below for more information).

Here the details:

*Date and time*: *25th of February 2026, 4:45 pm (CET)*

*Title*: "Mean Curvature Flow: from Euclidean space to the Heisenberg group"

*Abstract*: How do shapes evolve when driven by their mean curvature? In
Euclidean space, Huisken’s classical theorem ensures that convex surfaces
become spherical sub-Riemannian context, analyzing the flow for mean convex
hypersurfaces. We will discuss the problem of self-similarity in this
setting and present a recent result: the Pansu sphere, despite being the
candidate isoperimetricrole of self-shrinkers as models for singularities.
Then, we will move to the sub-Riemannian context, analyzing the flow for
mean convex hypersurfaces. We will discuss the problem of self-similarity
in this setting and present a recent result: the Pansu sphere, despite
being the candidate isoperimetric profile of H^1, is not a self-shrinker.
This reveals a striking divergence from the Euclidean intuition, where the
static isoperimetric solution and the dynamic evolution profile coincide.

*Keywords:* Mean Curvature Flow, Heisenberg Group, Mean Convexity

*Information to attend in person*
The seminar will take place at the building U9-Koinè, Università degli
Studi di Milano Bicocca; room U9-11.
