[Dottorcomp] Insalate di Matematica - E. Bubani 25/1/2023

[Mbs Insalate Di Matematica]

Dear all,

As part of the series of seminars "Insalate di Matematica", *Elia
Bubani* (Universität
Bern, Mathematisches Institut) will give a talk.
The speaker will deliver the talk *in presence* and the meeting will also
be broadcasted *online* (see below for more information).

Here the details:

*Date and time*: 25th of January 2023, 4:00 pm (CET)

*Title*: "The Modulus of a curve family"

*Abstract*: Let's try to set up a geometric problem in the Euclidean plane:
consider a square [image: Q = (0, 1) \times (0, 1)] and a rectangle [image:
R_{a,b} = (0, a) \times (0, b)]. The Riemann mapping theorem guarantees
that [image: Q] and [image: R_{a,b}] are conformally equivalent. Any
conformal homeomorphism between the square and the rectangle extends
homeomorphically to the boundary. One might ask whether it is possible to
do this in
such a way that the horizontal edges of [image: Q] are mapped to the
corresponding horizontal edges of [image: R_{a,b}] ,and analogously for the
vertical edges of the rectangles.
In order to answer such questions we shall introduce the Modulus of a curve
family.
This tool has been relevant for the notion of Quasiconformal maps and
related theory.

*Keywords*: Conformal geometry, Modulus of a curve family, Quasiconformal
maps

*Information to attend in room 3014*
The seminar will take place in room 3014, at the building U5-Ratio,
Università degli Studi di Milano Bicocca.
