» Title:	The Probability That A Matrix Of Integers Is Diagonalizable
» Abstract:	The presenters investigate the question of the probability that a randomly chosen n by n matrix over the integers is diagonalizable. Such a probability is couched in terms of a variant on "natural density." Specifically, let n and k be positive integers, A(n,k) the number of diagonalizable n by n matrices over the integers with entries in the interval [-k,k], and B(n,k) the number of n by n matrices over the integers with entries in the interval [k,k]. Then, for fixed n, the presenters consider the value of A(n,k) / B(n,k) as k goes to infinity. To this end, they examine a (more computationaly amenable) lower bound on this probability by studying the number of n by n matrices over the integers in the interval [-k,k] that have n distinct eigenvalues.

The Sunjay Times is a collection of my thoughts, my writing scratch pad. Best taken with a dose of reality after a meal, commonly known to User 2.0 as a "weblog". I'm passively looking for guest authors as well, if you like the theme and want to contribute, please contact me. Check it out here: http://times.jayliew.com

JAY S. LIEW received his B.S. degree in computer science from the University of Louisiana at Monroe in 2004 with a minor in mathematics. He is currently a software engineer for Websense, Inc., where he reverse engineers proprietary protocols and conducts quality assurance testing. His research interests include nonlinear dynamical systems and the theory of computability and complexity. He believes in attempting the impossible because it is only absurd until someone achieves it, and wants to change the world through the use of technology. In his spare time, he sleeps when necessary. Jay S. Liew is a member of the Association of Computing Machinery, Institute of Electrical and Electronics Engineers and has been inducted into various honor societies including Upsilon Pi Epsilon, Kappa Mu Epsilon, Alpha Lambda Delta, and Phi Eta Sigma.

Yes, this is my web page and I will post whatever I want to post. The following are a collection of links to places on the web that contain information I find interesting or useful. (or stuff that doesn't really fit anywhere else on this page)

Miscellaneous trivia about me

The awesome company I am currently working for: Websense, Inc. We kick butt, and we're located in lovely San Diego.

The place where I shed lots `o sweat to get my major and minor: The University of Louisiana at Monroe. Had lotsa good times and met lotsa good southern folks. Hey y'all!

In Louisiana, I worked for Horizons Bank, who then merged with American Bank to become American Horizons Bank, who then (last I heard) got bought out by Iberia Bank. Although I took care of the technical side of things, I got to know many good folks in the financial industry that I still keep in touch with.

Dr. Andrew Hetzel. He and I met when he, as a newly minted Ph.D from the University of Tennessee, Knoxville started teaching at the University of Louisiana at Monroe (ULM). It was a brief encounter, as I was finishing up my last 1 or 2 semesters when he first started teaching there, so technically there wasn't a student-teacher relationship where I needed him to give me a good grade at the end of the class.
None of the classes he taught at ULM intersected with the list of classes I had to take for my degree. Nevertheless, I snuck into his math classes (which he didn't seem to mind at all) and sat on the front row. It was truly a refreshingly spectacular experience, for me to learn from a teacher so enthusiastic, passionate, non-discriminatory (I was a poor broke student) who had exceptional problem-solving skills who can relate math to computer science, physics, and everything else on the planet, who also had interesting ways of getting the class attention on an early Monday morning (not that I needed it, but everyone else did).
I ended up working with Andrew on an original math research project, where I snagged a free all-expense-paid trip from the ULM math department to Phoenix, AZ to present our research findings at the annual national math conference. Yes, you heard me right, the national math conference. It was awesome (in a quirky geeky way, which I am not ashamed to admit that I am). A lot of work, but the experience was rewarding. Because of my work on the research project, I was recognized as the College of Arts & Science's outstanding student in 2004.
If you have the opportunity to take a class from Andrew, I would so definitely recommend it (hell, if it wasn't for distance, time, and cost, I'd take your class for you from this guy). Andrew has since then moved back to Tennessee and now teaches for the Tennessee Tech University.

These are some quotes I read over and over to remind myself. I hope you may find them helpful, as much as I did.

You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. The danger lies in refusing to face the fear, in not daring to come to grips with it. You must make yourself succeed every time. You must do the thing you think you cannot do. — Eleanor Roosevelt

Genius is one percent inspiration and ninety-nine percent perspiration. — Thomas Edison

You can have anything you want if you want it badly enough. You can be anything you want to be, do anything you set out to accomplish if you hold to that desire with singleness of purpose. — Abraham Lincoln

As long as you're going to think anyway, think big. — Donald Trump
