Description: The aim of Math 6501 is to present classic results in graph theory and combinatorics, showcasing different facets of these areas and demonstrating how tools from various branches of mathematics can be used to solve combinatorial problems, and conversely, how combinatorial ideas can help address problems in other fields.

Location: East Campus the 5th Building 5106 Description: The course offers an introduction to arithmetic combinatorics, a modern area of mathematics that lies at the interface of combinatorics, num…
