### Graduate Student Seminar, 4:30 pm November 8, 2004; HH127

#### Speaker:

Julie Bergner
#### Title:

An Introduction to Algebraic Theories
#### Abstract:

The notion of an algebraic theory provides a basis-free way of
discussing algebraic structures such as monoids, groups, and commutative rings.
In addition, an algebraic theory can be used to describe an algebraic structure
on a topological space. This talk will include some (very basic) category
theory background, the definition of algebraic theories, and examples
illustrating how they provide a concise way of expressing algebraic structures.
In particular, I will discuss the ways in which algebraic theories and a
generalization of them have been a useful tool in my research.
