### 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.

## Proper Maps and (Quasi) Projective Varieties

I’m back! So let’s get down to business. What I really want to talk about is the Riemann Roch Theorem. You may wonder why, since it has already been discussed here , but there have been vast generalizations of this … Continue reading
