Graduate Student Algebraic Geometry Seminar

Professor A.J. de Jong, Columbia university, Department of Mathematics.

At MIT I started having a graduate student algebraic gometry seminar. I have decided to put up this page to archive the topics of previous seminars. However, I have only gone as far back as the first seminar I organized here at Columbia.

Here is the link to the webpage with information.

-----------------------------------------

In the Spring of 2016 the topic of the seminar was the stable rationality and the diagonal as discussed by Voisin, Totaro, culminating in a discussion of the recent paper by Hassett, Pirutka, and Tschinkel. Please see the old webpage and the actual webpage with information.

-----------------------------------------

In the Fall of 2014 the topic of the seminar was tropical geometry and in particular the proof of the Brill-Noether theorem using tropical geometry. It was a really fun topic to do! Here is the link to the webpage.

-----------------------------------------

In the Spring of 2014 I organized a literature seminar for graduate students. Here is the link to the webpage.

-----------------------------------------

In the Fall of 2013 I organized a graduate student seminar on derived categories. Take a look at the webpage.

-----------------------------------------

In the Spring of 2012 I organized a graduate student seminar on crystalline cohomology. Take a look at the webpage. See graduate student seminar in algebraic geometry for the original course listing.

-----------------------------------------

During the Fall of 2011 I organized a graduate student seminar on Brauer groups in Algebraic Geometry. Take a look at its webpage for more information. See graduate student seminar in algebraic geometry for the original course listing.

-----------------------------------------

During the Spring of 2011 I organized a graduate student seminar on Derived Categories in Algebraic Geometry. Take a look at its webpage for more information. See graduate student seminar in algebraic geometry for the original course listing.

-----------------------------------------

During the Fall of 2010 I organized a graduate student seminar on Hodge Theory in Algebraic Geometry. Please find the original web-page with list of talks on this page. See graduate student algebraic geometry seminar for the original course listing.

-----------------------------------------

During the Summer of 2010 I organized a graduate student seminar on Algebraic Geometry. The idea was for the students and I to come up with problems in algebraic geometry, to democratically choose a problem, and try to solve that problem. If stuck or solved we start over. The rules will be that the problems

I moderated the discussion throughout. One goal of this format is to build communication skills, discover standard methods in algebraic geometry and to try to give an idea what it means to do something ``new''. We had biweekly meetings of about an hour.

-----------------------------------------

During the Spring of 2010 semester the graduate student algebraic geometry seminar was a literature seminar. Please look at this page for a list of papers. We met on Fridays from 3:30-4:30 (+/- 15 minutes) in Room 312 of the Mathematics Building. The first organizational meeting was a short meeting on Friday, January 22, 2010 where we divided up the talks. List of talks with names and topics is here.

-----------------------------------------

During the Fall of 2009 the graduate student algebraic geometry seminar was on algebraic stacks. We met Fridays from 10:30-12:30 in Room 312 of the Mathematics Building. I gave the first two lectures to introduce the material, the first one on Friday, September 11, 2009. After the first two lectures the graduate students gave lecture on examples of algebraic stacks, especially those which are relevant to moduli theory, and more generally arithmetic algebraic geometry. Here is the (preliminary) list of topics for lectures by students: pdf | dvi | tex. List of talks (see file above for more details):

There is a guide to the literature, written by Jarod Alper, see stacks_guide.pdf. This is now also a chapter of the stacks project.

-----------------------------------------

In the summer of 2009 we had a graduate student algebraic geometry seminar on Intersection Theory, organized by Qi You and myself. We worked through classical intersection theory including Grothendieck-Riemann-Roch.

-----------------------------------------

In the Spring of 2009 the graduate student algebraic geometry seminar was organized by Maksym Fedorchuk and me. The topic was be Introduction to higher dimensional algebraic geometry. Here is some more information:

-----------------------------------------

In the Fall of 2008 the graduate student algebraic geometry seminar is organized by Frans Oort and me. The topic was ``Abelian Varieties over Finite Fields''. Main Literature Sources, with links:

-----------------------------------------

In the fall of 2008 the graduate student algebraic geometry seminar was about weighted projective spaces, quasi-smooth hypersurfaces in them, and how to compute their cohomology. Ostensibly the title was "Problems for graduate students". I gave all of the lectures myself.

-----------------------------------------

In the Summer of 2008 we had a graduate student seminar on A^1-homotopy theory where all the lecture were given by Bhargav Bhatt.

-----------------------------------------

The Fall semester of 2007 we discussed motives in the graduate student algebraic geometry seminar. Here are some related documents:

-----------------------------------------

In the summer of 2007 the graduate student algebraic geometry seminar was about GIT and Hodge theory.

-----------------------------------------

In the Spring of 2007 the topic of the graduate student algebraic geometry seminar was "Rational curves on higher dimensional algebraic varieties -- in particular low degree hypersurfaces". Jason Starr and I alternated giving the lectures, and we worked through the paper "Low degree complete intersections are rationally simply connected" available on Jason Starr's webpage.

-----------------------------------------

Fall 2006: Topic was deformation theory.

-----------------------------------------

Spring 2006: Topic was algebraic stacks.
