The number theory group at Oklahoma State University has established a thriving program of research, including a regular seminar series featuring lectures of both a research and expository nature by the resident number theorists, as well as frequent lectures by distinguished young and senior number theorists from around the country.
Number theory is famed not just for the beauty of its theorems, but for the enormous wealth and variety of techniques involved in discovering and proving these theorems.
Our faculty is prepared to offer courses in algebraic number theory, class field theory, analytic number theory, the arithmetic of elliptic curves as well as other arithmetic algebraic varieties, p-adic analysis, automorphic and modular forms, discrete subgroups of algebraic groups, computational number theory, as well as many other subfields of number theory.

 Introduction to social network methods:  Chapter 14:  Automorphic equivalence
Automorphic equivalence is not as demanding a definition of similarity as structural equivalence, but is more demanding than regular equivalence.
Automorphic equivalence asks if the whole network can be re-arranged, putting different actors at different nodes, but leaving the relational structure or skeleton of the network intact.
Having selected a number of partitions, it is useful to re-run the algorithm a number of times to insure that a global, rather than local minimum has been found.

 [No title]
L-functions have been used for over a century in number theory; Langlands isolated the correct analogue from representation theory (so-called "automorphic" L-functions) and was the first to understand the general picture.
As an example of why one might expect some sort of connection between Lie groups and number theory, consider the Galois group G = Gal(K/L) where K is an algebraic closure of a number field L. Number theorists are very interested in representations of K. G is a profinite group (projective limit of finite groups).

 Robert Langlands' work - automorphics forms
The letter to Weil included a number of striking conjectures which eventually changed much of the direction of research in automorphic forms.
Some of their consequences were explained in a graduate course given at Princeton in the spring of 1967, and then things were put in a somewhat wider context in a series of lectures at Yale later that Spring.
These two observations underline that functoriality arose in an attempt to find a nonabelian class-field theory under the influence of the view, which arose in the early sixties, that much of the theory of automorphic forms could and should be treated in the context of group representations.
