Title: " Tritangent planes to space sextic curves: a tropical viewpoint "
Abstract:
A classical result due to Clebsch from the mid-nineteenth century confirms that
every complex space sextic curve (given as an intersection of a quadric and a cubic surface in projective 3-space)
has exactly 120 tritangent planes. In this talk we will show how to use combinatorial methods arising from tropical
geometry to revisit this classical problem and perform the analogous count over the reals and extensions thereof.
This is joint work with Yoav Len, Hannah Markwig and Yue Ren (arXiv:2512.24277).

Schedule: 16:00 - Rome Time
Where: Conference Room 1101 "C. D'Antoni"
Title:" A geometric view on congruences of modular forms "
Speaker: Bordignon Paolo - Leiden University
Abstract:
The study of Fourier coefficients of modular forms has a long and rich history,
from Ramanujan’s conjectures to the modularity theorem relating modular forms to elliptic curves.
In this talk, we first present the arithmetic–geometric viewpoint on modular forms provided by modular curves,
and use it to study certain congruences. These may first appear as numerical coincidences,
but in fact hide structures arising from the geometry and cohomology of modular curves in p-adic setting.

COMPLEX ANALYSIS SEMINAR
Date: 10 March 2026
Schedule: 16:00 - Rome Time
Where: Conference Room 2001
Title: " Non-Kaehler metrics on compact manifolds "
Speaker: Liviu Ornea - University of Bucharest
Abstract:
Abstract: I shall recall the definitions and main properties of several Hermitian non-Kaehler metrics
(Gauduchon, puriclosed, balanced, locally conformal Kaehler),
then discuss the possibility of their simultaneous existence on the same compact manifold.
Based on joint works with Misha Verbitsky.

DIFFERENTIAL EQUATIONS SEMINAR
Date: 10 March 2026
Schedule: 14:30 - Rome Time
Where: Conference Room "R. Dal Passo "
Title: " A notion of fractional area in codimension 2 "
Speaker: Nicola Picenni - Pisa University
Abstract:
We consider a notion of fractional s-area for codimension 2
surfaces in a closed Riemannian manifold or the Euclidean space, which can
be seen as an extension of the fractional perimeter to higher codimension.
The definition involves a minimum problem over a class of circle-valued
maps having prescribed singularities on the given surface. We discuss
various properties of the s-area when s is fixed, and we show that when s
tends to 1 it Gamma-converges, with coercivity, to the classical area in
the framework of currents.
The talk is based on a joint project with Michele Caselli and Mattia
Freguglia.
