I'm attempting to collect on this page various notes that I've written at various times. As of now, this list is quite incomplete.

Algorithmic Number Theory These notes were written as part of a seminar that I ran during Fall 2000 at CSUN.: Algorithmic Number Theory I Cyclicity of units of Z/p^n for odd p, Carmichael numbers.; Algorithmic Number Theory II Primality testing, Solovay-Strassen test, Quadratic Reciprocity.; Algorithmic Number Theory III Miller-Rabin test.; Algorithmic Number Theory IV Factorization: Pollard's p-1 test, and Lenstra's elliptic curve algorithm.
Division Algebras These are some expository articles I wrote on division algebras.: Division Algebras Should be readable by high school students interested in mathematics and undergraduate students in science and engineering.; Some notes on the quaternions. Notes for a talk I gave at AU-KBC (Chennai) to engineers on how the quaternions can be used to quantify 3-d rotation.
