Please join the Math department in welcoming Fred Galetto as he will give a talk on "Jets of graphs"

Abstract - Jets can be thought of as "dynamic" points that carry, in addition to positional data, information such as velocity, acceleration, etc. The jets of a geometric object (such as a curve or surface) form a space that can be defined by explicit equations. When the equations are squarefree monomials of degree two, they are naturally associated to graphs. This allows us to define a notion of jet graphs that can be studied combinatorially. After introducing the basics of jets, I will present some results about jet graphs motivated by questions of combinatorial commutative algebra.

A reception will be held before at 4PM in King 203, followed by the talk in King 239.
