### 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.

## MaBloWriMo?

So, anyone who spends much time on the internet, or else hangs out with liberal arts types, is probably aware of NaNoWriMo, National Novel Writing Month in November. Now, if you’re a fifth year grad student or so, there’s NaDiWriMo, … Continue reading
