Low Dimension Lie Algebra Dimension Reduction by Modding by the Center<br />
Nick Benthem<br />
Grand Valley State University<br />
We investigate reducing the order <strong>of</strong> real low dimensional Lie algebras by modding by the center.<br />
We find the isomorphism between the reduced algebra and one <strong>of</strong> the non-decomposable Lie algebras<br />
and explain why in certain cases the reduced algebra decomposes.<br />

Markov Chains in Literature: Re-Exploring Markovs Original<br />
Applications Using Modern Technology<br />
Anne French<br />
Austin Peay State University<br />
Markov chains have numerous applications throughout mathematics and science, which is something<br />
the creator <strong>of</strong> the chains never thought was possible. Andrey A. Markov thought that his<br />
chains would only be applicable in the exploration <strong>of</strong> literature. His love <strong>of</strong> poetry led him to use<br />
Markov chains to study the alteration <strong>of</strong> vowels and consonants in Russian literature as a hobby.<br />
This presentation demonstrates how the analysis <strong>of</strong> literature using Markov chains and computer<br />
programming can be used to reveal the origination <strong>of</strong> the nonsense texts <strong>of</strong> the mathematician<br />
Charles Dodson, who is also known as Lewis Carroll.<br />

Investigating the Mapping Properties <strong>of</strong> a Certain Class <strong>of</strong> Harmonic<br />
Functions on the Unit Disc<br />
Cory Medin<br />
Austin Peay State University<br />
A good departure point for investigating harmonic polynomials is to study certain classes <strong>of</strong> harmonic<br />
functions. In particular, we compare the mapping properties <strong>of</strong> a certain family <strong>of</strong> harmonic<br />
functions with the mapping properties a certain family <strong>of</strong> Schlicht functions on the unit disc.<br />

Benford Melodies: A Senior Thesis on Stochastic Composition<br />
Nathaniel Card<br />
Carthage College<br />
Benfords Law can be applied to many things: addresses, stock prices, and river lengths; however,<br />
in this presentation we will explore using Benfords Law to both analyze and create melodies. The<br />
principal question being thus: do most melodies follow Benfords Law by the very nature <strong>of</strong> musical<br />
composition and counterpoint, or would composing melodies using Benfords Law create truly<br />
original sounding stochastic music.<br />
