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.

Monodromy Representations
A departure from directly working with varieties, we’re going to do something that’s strictly topological (at first glance) but which really has deep and important connections with Hodge theory. We’re going to talk about monodromy and monodromy representations. Let be … Continue reading
Beauville makes a list
If you like Hyperkähler manifolds (and who doesn’t?) go check out Beauville’s new preprint: Holomorphic symplectic geometry: a problem list. It’s nice and short survey of the basic facts of hyperkähler manifolds, including a bunch of conjectures and open problems … Continue reading

The Hodge Theorem
Previously, we talked a bit about the category of Hodge structures, and did some basic constructions. However, I’d claimed that this was algebraic geometry (at least, in the categories on the post) so today, we’ll talk about a LOT of … Continue reading

Algebraic Geometry Belongs to Sheaves
Over at the n-Category Cafe, Tom Leinster has written an excellent post pointing out that sheaf theory is NOT a subfield of algebraic geometry. I feel I have a few things to add, not enough for a long post, but … Continue reading

Hodge Structures
Back to blogging for a bit, though likely infrequently. Doing a new series that might count as AG from the beginning, so I’ll put it up there once I’ve got a couple done. We’re going to start doing some Hodge … Continue reading
