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.</div><div dir="auto"><br></div><div dir="auto"><div dir="auto"><font color="#000000"><u>Keywords:</u></font> sub-Riemannian geometry, Schrödinger operator, surfaces, characteristic points, characteristic foliation<div dir="auto"><br></div></div><div dir="auto"><br></div><div dir="auto"><div dir="auto"><u><b>Information to attend in room 3014</b></u></div><div dir="auto">The seminar will take place in room 3014, at the building U5-Ratio, Università degli Studi di Milano Bicocca.</div><div dir="auto"><br></div><div dir="auto"></div><div dir="auto"><u><b>Information to attend online<br></b></u></div><div dir="auto"><a href="https://unimib.webex.com/unimib/j.php?MTID=m101728a0c0258813b6aa97783fb11fad" target="_blank">https://unimib.webex.com/unimib/j.php?MTID=m101728a0c0258813b6aa97783fb11fad</a> (password: insalate, 46725283 from phones)<a href="https://unimib.webex.com/unimib/j.php?MTID=m101728a0c0258813b6aa97783fb11fad" target="_blank"></a></div><a href="https://unimib.webex.com/unimib/j.php?MTID=m3c536ba5a33f71bb9d6a3bc9b00992ad" target="_blank"></a><div dir="auto"><div id="m_-8149149258146314273m_1557104255583827781m_-4439392858642327092m_5555831848437307896gmail-:183" style="direction:ltr;margin:8px 0px 0px;padding:0px;font-size:0.875rem;font-family:"Google Sans",Roboto,RobotoDraft,Helvetica,Arial,sans-serif"><div id="m_-8149149258146314273m_1557104255583827781m_-4439392858642327092m_5555831848437307896gmail-:17t" style="font-variant-numeric:normal;font-variant-east-asian:normal;font-variant-alternates:normal;font-kerning:auto;font-feature-settings:normal;font-stretch:normal;font-size:small;line-height:1.5;font-family:Arial,Helvetica,sans-serif;overflow:hidden"><div dir="ltr"><div dir="auto"><div dir="auto"><div dir="auto"><div dir="auto"><br></div><div dir="auto">For further information, please visit our website: <a href="https://sites.google.com/view/insalate-di-matematica" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">https://sites.google.com/view/insalate-di-matematica</a> or contact us at <a href="mailto:insalate.matematica@unimib.it" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">insalate.matematica@unimib.it</a>.
