From Observation, to Pattern, to Conjecture, to Proof: A Simple Theorem from Calclulus and Geometry
Jon Hebert
Mathematics Department, UL Lafayette
Abstract: In this talk we will explore a common observation made by calculus students and attempt to make a more general claim. We will do so by examining other cases, looking for a pattern, forming a conjecture from that pattern, and finally, proving our conjecture.

Descartes and Fermat: an unlikely collaboration
Caleb MacDonald
Mathematics Department, UL Lafayette
Abstract: Rene Descartes and Pierre Dr Fermat's mutual enmity is well known and was exacerbated by their near simultaneous publications of methods for finding tangents. We will work through a sample problem using Descartes circle method, Fermat's line method, and what has been termed 'Descartes line method', but which is really a clarification of Fermat's method. Time allowing we will gesture in the direction of a derivation of the power rule using this line method.

Algebraic Geometry: What is it and how is it used?
James Kimball
Mathematics Department, UL Lafayette
Abstract: A central theme in Algebraic Geometry is the study of solutions of systems of polynomial equations in one or more variables. The solutions of these systems of equations form geometric objects called varieties. The corresponding algebraic objects are called ideals. In this talk, we will introduce these objects at the undergraduate level and provide many concrete and motivating examples. With these and algorithms for manipulating systems of polynomial equations, we can introduce a few fundamental results in the field of Algebraic Geometry. Time permitting, we will introduce a few of the more interesting applications, such as robotics and errorcorrecting codes.

A Quick Introduction to Goedel's Theorem
Arturo Magidin
Mathematics Department, UL Lafayette
Abstract: Goedel's Theorem states that in certain types of axiomatic systems, we can either prove both a proposition and its negation, or else there are propositions that can neither be proven nor disproven. It was a major accomplishment, and Goedel is often called the greatest logician since Aristotle.
We will give a quick overview of the history that led to Goedel's Theorem, as well as making precise exactly what it says (and what it does not say); we will also explain how the proof works. If time permits, we will go into some of the details of the proof.

The Cantor Set in the Context of Totally Disconnected Spaces
Cody Nash
Mathematics Department, UL Lafayette
Abstract: The Cantor Set is a subset of the set of real numbers that has many very interesting properties. Georg Cantor was the first to introduce the Cantor Set. The Cantor Set was used extensively by Cantor and his colleagues when they were creating new, fundamental ideas in the field of pointset topology. One of these interesting topological properties of the Cantor Set is that it is a totally disconnected space. In this talk we will review some introductory material to aid in understanding what a totally disconnected space is. This introductory material will include equivalence relations, some ideas about what a topology on a set is, and some terminology used in the field of topology. After the introductory material, we will discuss what it means to be a totally disconnected space. This will lead to two supplementary theorems which will aid us in proving that the Cantor Set is a totally disconnected space.
