STARTING SHORTLY: Invitation to the joint ICTP-SISSA Colloquium by Prof. Luigi Ambrosio on "On some variational problems involving functions with bounded Hessian", TODAY, Wednesday 12 April in the Budinich Lecture Hall at 16:00

[Infopoint]

Dear All,

You are most cordially invited to the ICTP-SISSA Colloquium by Prof. 
Luigi Ambrosio, Director of Scuola Normale Superiore, on "On some 
variational problems involving functions with bounded Hessian".

The Colloquium will take place at the ICTP, in the Budinich Lecture 
Hall, TODAY,  Wednesday 12 April at 16:00 hrs CET and will also be 
livestreamed from the ICTP website.

*Biosketch:* Luigi Ambrosio is Full Professor of Mathematical Analysis 
at Scuola Normale Superiore of Pisa since 1997. In 2019 he has been 
nominated Director of Scuola Normale Superiore. Prof. Ambrosio is a long 
term visiting scientist in the Max Planck Institute of Leipzig, the 
Massachusetts Institute of Technology, the ETH of Zurich, and the 
Institute Henri Poincaré of Paris. Prior to joining Scuola Normale 
Superiore, Prof. Ambrosio has been Full Professor at the University of 
Pisa and at the University of Benevento, both in Italy.

Prof. Ambrosio's scientific interest include the calculus of variations, 
the Geometric Measure Theory; the Transportation Theory and their 
application to partial differential equations. For his research he has 
been awarded numerous prizes, including which the "Riemann prize of the 
Riemann International Mathematics School" (2022); the Balzan Prize for 
the achievements in the theory of partial differential equations (2019); 
the Blaise Pascal Medal of the European Academy of Sciences (2019); the 
gold medal for achievements in Mathematics awarded by the XL National 
Academy of Sciences, Italy (2015).

*Abstract*: In this talk Prof. Ambrosio will illustrate new questions, 
at the interface between Calculus of Variations and Geometric Measure 
Theory, motivated in a broad sense by the more applied machine learning 
community. More specifically, he will deal with second-order variational 
problems in the setting of functions with bounded variation and study 
the extremal properties of continuous and piecewise affine functions in 
the unit ball of a suitable energy, used as a regularization term in the 
applied community. In connection with this, a fine approximation result 
by piecewise affine function has been investigated.

The talk will be followed by a question/answer session and light 
refreshments will be served in the lobby shortly after. For more 
information, please see https://indico.ictp.it/event/10298

Looking forward to your participation.

With best regards,

Marianna Tonutti
