Ok, my plans to post regularly seem to have died a horrible, horrible death as I begin studying for orals in earnest and preparing to head to a conference. Thus, I’m just giving up. Don’t expect much for the rest of June. Hopefully July will work out better. We’ll see.

### 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.
