I should probably introduce myself (and start writing as well!). I’m Matt, a first-year grad student at the University of Chicago. I’m interested in algebra, geometry, and topology, but I also find various topics in theoretical CS and in logic and set theory really neat — so I doubt there will be much uniformity in the topics I write about!

### About this blog

Rigorous trivialities is a web log about mathematics, but especially geometry, broadly construed. Contributors will be Charles Siegel, Jim Stankewicz and occasionally Matt Deland. Charles specializes in algebraic geometry, topology and mathematical physics. Jim specializes in arithmetic algebraic geometry. Matt has transitioned from algebraic geometry to work in industry.
