Università degli Studi Roma Tor Vergata
Dipartimento di Matematica
Geometry Seminar
Date: 17 February 2026
Schedule:
14:30 - 15:30 Rome Time
Where: Conference Room 1101 "C. D'Antoni"
Speaker: Emmanuel Kowalski - ETH Zürich
Title: " Exponential sums, jacobians and graphs "
Abstract:
Exponential sums over finite fields are essential ingredients in the solution of many arithmetic problems.
Their study often relies on algebraic geometry, and especially on Deligne's Riemann Hypothesis over finite fields,
which reveals deep structural features of these sums. In turn, one can exploit these to construct some remarkable combinatorial objects.
The talk will provide a survey of these various aspects. (Joint works with A. Forey, J. Fresán and Y. Wigderson)

DIFFERENTIAL EQUATIONS SEMINAR
Date: 17 February 2026
Schedule: 14:30 - Rome Time -
Where: Conference Room "R. Dal Passo "
Title: " Horospherical billiards "
Speaker: Rafael Ruggiero - PUC Rio de Janeiro
Abstract:
We introduce the concept of horospherical billiard in the
universal covering of a compact surface without focal points and prove some
rigidity results assuming the existence of some geometric first integrals.

Algebra and Representation Theory Seminar
Date: Friday 20 February 2026
Schedule:
FIRST SEMINAR 14:30 Rome Time
SECOND SEMINAR 16:00 Rome Time
Where: Conference Room 1201 - R. Dal Passo
FIRST SEMINAR 14:30 Rome Time - joint session with the "Topology Seminar" -
Speaker: Yasushi IKEDA - I.H.E.S.
Title: "Argument shift method on algebra U(gl(d)) "
Abstract:
The argument shift method is a simple but efficient way to produce a commutative subalgebra in a Poisson algebra, in particular
in the symmetric algebra of a Lie group. Its main ingredient is an operator on the Poisson algebra that generates the elements
of the commutative subalgebra by acting on its center.
In my talk I will describe an analogous operator on the universal enveloping algebra of gl(d),
and show, why it satisfies a similar property.

SECOND SEMINAR 16:00 Rome Time - joint session with the "Topology Seminar" -
Speaker: Georgy SHARYGIN - I.H.E.S.
Title: " The symmetries of the full symmetric Toda system and Lie-Bianchi "
Abstract:
The full symmetric Toda system is a Hamilton system on the space of real symmetric matrices, given by the Lax equation L' = [M(L),L] ,
where M(L) is the naïve antisymmetrisation of the symmetric matrix L (deleting the diagonal and inverting the sign of the lower-triangular half).
This system turns out to be Liouville-integrable and even super-integrable.
In my talk I will prove that it satisfies one more integrability criterion, the Lie-Bianchi criterion, based on the study of its symmetries.
