### 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.

## Notes are posted

Just a quick little thing before the conference talks start, and I’m texing in earnest, the rest of the notes I was able to take during the summer school are now posted on my Notes page, here. They’re a bit … Continue reading

## ICTP Day 12 – End of the Summer School

The summer school is over. Tomorrow begins the conference, including talks from such luminaries as Arapura, Illusie, Griffiths…and that’s just the first three talks tomorrow. I’ll be talking on Thursday at 17:05, and until then, it’s polishing time for my … Continue reading

## ICTP Day 11

Today was the penultimate day of the summer school. Once it finishes, there will be a conference, and things go through Friday, so all-in-all, there will be 15 days in this series. And here’s today’s notes:

## ICTP Day 10

And these posts are getting shorter, as the talks that I’m even attempting to take notes in are finishing. The other talks are good, they’re just moving very, very fast and given a choice between learning and notetaking, I’m choosing … Continue reading

## Greatest Moment

We just had the greatest moment of the summer school, and I doubt it will be topped. Mark Green is giving lectures and defines hypercohomology, and then mentions the musical “The Sound of Music” and quotes from it: Raindrops on … Continue reading

## ICTP Day 9

So, today a few lecture series finished up, and I’ve posted notes from some of the older ones in pdfs on my personal website. And here’s the notes, which I’ll admit are getting spottier, as Griffiths is lecturing from his … Continue reading

## ICTP Day 8

Today was a half day, and we finished Carlson’s series. I think this afternoon I’ll clean some things up and maybe post notes from the finished series on my website, along with links from here. In any case, here are … Continue reading

## ICTP Day 7

Today we kept going with the advanced topics, and started Shimura varieties, though that one went VERY fast. As always, comments and corrections are welcome!

## ICTP Day 6

Today we started the third part of the summer school: Algebraic Cycles, Arithmetic aspects of Hodge Structures-Mumford-Tate Groups. There was actually quite a bit of review today, which surprised me, and instead of taking notes on the definition of Hodge … Continue reading

## ICTP Day 5

Today was the last day of “basic Hodge theory”…so we talked about intersection cohomology and the decomposition theorem and the like. I admit to losing the thread of the lectures a couple of times (marked in the notes) and not … Continue reading
