Although I have not studied math for almost 20 years I have studied math at GA State and GA Tech. I am trying to relearn what I once thought I knew. I was quite proficient in topology and matrix analysis. I did research in qualitative matrix analysis, Markov chains, Perron Compliments. I was in the PhD program at Tech but left with a masters due to family matters. I have recently taken a job as a part time instructor at GPC, a two year community college, and I am doing my best to refresh my knowledge. My biggest difficulty is learning my way around all of the typesetting.
