| Representation theory and arithmetic geometry |
|
In this talk I will talk about the relation between representation theory and arithmetic geometry. In particular, I will try to discuss several examples that connect representation theory and arithmetic geometry closely. Then if time permits, I will give a brief introduction to trace formula approach, which is the most powerful and promising tools in this field. |

| Asvin Gothandaraman |
| Modular forms and class groups |
|
In preparation for Thursday's talk, I will review some concepts from Galois Cohomology. I will also give an introduction to the Herbrand-Ribet theorem. |

| ABC's of Shimura Varieties |
|
I'll present some of the formalization of Shimura varieties, with a strong emphasis on examples so that we can all get a small foothold whenever someone says the term Shimura variety. |

| Primality Tests Arising From Counting Points on Elliptic Curves Over Finite Fields |
|
We will give some background on counting the rational points on an elliptic curve over a finite field. Then we will apply this theory to a couple of specific elliptic curves and explain how it results in (impractical) primality tests. |

| Golomb Topologies and Infinitely Many Irreducibles |
|
In 1955, Furstenberg gave a proof of the infinitude of primes by imposing a topology on Z. Under this topology, all open sets are infinite, but if you assume only finitely many primes then {1} is open. A new, similar, topology was introduced by Golomb in 1959, which turned Z^+ into a connected Hausdorff space. A general Golomb topology on a domain R was introduced by Knopfmacher and Porubský in 1997. I will draw on a paper of Clark, Lebowitz-Lockard, and Pollack, and discuss interesting properties of these topologies, and how they relate to properties of the domain R. |

| Perspectives on Rational Points |
|
This talk is going to be an all-you-can-eat smorgasbord of techniques for finding rational points on curves. |

| Brandon Boggess |
| Squares in Arithmetic Progressions |
|
We will see how results about rational points on curves can say something about integers in arithmetic progressions. Media:mar_24_slides.pdf |
