### 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.

## Invariants and Solving Polynomials

I’m back from Ohio, and ready to get back to the math blogging. Had my preliminary exams (written quals) today, so that should explain the delay in posting. Instead of covering anything I saw at YMC (though I will likely … Continue reading

## YMC 2007

Ok, ok, I didn’t post anything this past week. And I won’t be getting anything in on Monday, however, I have a good reason. This weekend, I’m off to the 2007 Young Mathematician’s Conference at Ohio State. So when I … Continue reading

## Polynomial Knots II

So last time, I talked about the basics of polynomial knots as individual objects. Now, we’re going to talk about their parameter spaces as well as the most important new knot invariant they have given us. So first off, we … Continue reading

## Polynomial Knots I

So I’m going to start out with something that I’ve been thinking about for about a year now, though not very hard. To begin with, a knot is an embedding of the circle into the three sphere, and for our … Continue reading

## Too much time on my hands

Hi, I’m Charlie. I’m starting graduate school in math at the University of Pennsylvania in the fall, and I clearly have way too much time on my hands, because I’ve decided to start a math blog and, worse, to drag … Continue reading
