[Insalate Di Matematica]

Dear all,

For the *next appointment* of the series of seminars "Insalate di
Matematica", *Lucia Tessarolo* (Laboratoire Jacques-Louis Lion) 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*: *5th of June 2024, 4:30 pm (CET)*

*Title*: "Schrödinger evolution on surfaces in 3D contact sub-Riemannian
manifolds"

*Abstract*: Sub-Riemannian geometry has emerged in the last twenty years as
an independent research domain, with motivations and ramifications in
several parts of pure and applied mathematics. In this talk, we will
introduce sub-Riemannian manifolds, with a focus on 3D contact
sub-Riemannian manifolds. We will be interested in surfaces embedded in
this kind of manifolds which, unlike in the Riemannian case, do not inherit
a sub-Riemannian structure, making the definition of geometric objects more
challenging. In particular we will give the definition of characteristic
points, which are the "bad" points on the surface, and of characteristic
foliation, which is a foliation of the surface given by the sub-Riemannian
structure. We will then talk about the Schrödinger evolution on this
foliation and we will see how the self-adjointness of the Schrödinger
operator near a characteristic point p depends on a curvature-like
invariant at p.

*Keywords:* sub-Riemannian geometry, Schrödinger operator, surfaces,
characteristic points, characteristic foliation

*Information to attend in room 3014*
The seminar will take place in room 3014, at the building U5-Ratio,
Università degli Studi di Milano Bicocca.
