This site is to highlight my online math contents that are scattered across a number of blogs.
I am a mathematics writer based in the United States. I write extensively on various mathematical subjects. My online mathematical writings are scattered across a number of blogs (all my math blogs are by subject). This website serves as an online hub of my mathematical contents.
I earned my PhD in mathematics from Auburn University. I did my dissertation in general topology under the direction of Gary Gruenhage. Here’s my entry in math genealogy. My Erdos number is 3, a measure for the degree of separation (in terms of publications of math papers). My Erdos number is through the following path:
