SUMMARY:Math Seminar Series
DESCRIPTION:
Combinatorics and Graph Theory\n
\n
Alexander Diaz-Lopez
from Villanova University will be speaking.\n
\n
The
seminar title is "Arithmetical
Structures on Graphs."\n
\n
This is a virtual
meeting. Contact Bruce E Sagan (bsagan@msu.edu)
for more information.\n
\n
Arithmetical structures
on finite connected graphs are generalization
of the Laplacian of a graph. Dino Lorenzini
originally defined them in order to answer
some questions in algebraic geometry, but
more recently, they have been studied on their
own, particularly with a combinatorics lens.
In this talk, we will discuss how to count
the number of arithmetical structures on different
types of graphs and discuss why it is
a hard but interesting question for other families.
If time permits, we will talk about their
corresponding critical groups.\n\n
