### 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.

## And the winner is…

Intersection theory! So in November, I will be attempting to post at least once a day on things like Chow groups, Chern classes, normal cones, positivity, intersection products, degeneracy loci, Grothendieck-Riemann-Roch, etc. Thanks to everyone who voted. Let’s see how … Continue reading
