After registering, you will receive a confirmation email containing
information about joining the meeting.

The talk is divided in 2 parts, the 1st part is for more general audience
and the 2nd part is on current research.

Part 1: What is GIT? Why pencils of plane curves?
Abstract: I plan to first give a quick introduction to geometric invariant
theory (GIT) as well as to describe what my motivation is for studying the
problem that I will discuss in Part 2.

Part 2: On the GIT stability of pencils of plane curves
Abstract: In the second part of the talk, I will present a possible
approach to the problem of classifying pencils of plane curves up to
projective equivalence via geometric invariant theory. In particular, I
will explain how the stability of a pencil is related to the stability of
its generators, to the log canonical threshold, and to the multiplicities
of a base point. And I will also discuss some relevant examples.
This will be hybrid seminar. All are very welcome to join either online or
in person. Venue: Luigi Stasi Seminar (ICTP Leonardo Da Vinci Building),
for those wishing to attend in person.
