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
