DATE  SPEAKER  TITLE AND ABSTRACT 
5 September
 Eran Crockett
 Representing lattices
Every distributive lattice can be embedded in the lattice of subsets of some set. Which modular lattices can be embedded in the lattice of submodules of some module? The answer to this question will require a detour into projective geometry. This talk will be accessible to beginning graduate students.

12 September
 Matt Evans
 Adjunction Junction
In Categories for the Working Mathematician, Saunders Mac Lane wrote "The slogan is 'Adjoint functors arise everywhere'." Consider this talk an attempt to convince you of this fact. My other goals are to introduce the notion of a natural duality and (time permitting) talk about my current research. This talk is accessible to all graduate students.

19 September
 Chris Eppolito
 Topoi
A topos is a category with internal structures resembling those in the category of finite sets. I will motivate the definition of topoi and (time permitting) explain the connections to some interesting nonstandard logic systems.

26 September  Ted Ofner  Train track maps
We will discuss train track maps: what they are, how they are known to exist, and how they can be used to understand outer space.

 Ulysses Alvarez
 Curvature
I will discuss and define a generalization of curvature which shares properties of sectional curvature in Riemannian Geometry.

 No Seminar
 Fall Break

24 October
 Patrick Milano  Mathematical music theory I'll survey some applications of math to music. Topics will include Euler's Tonnetz (a network of related musical tones) and a recent geometric approach due to Callender, Quinn, and Tymoczko. A crash course in the music theory will be included for the benefit of music novices.
