Revision as of 04:14, 1 February 2024
When: 2:30PM - 4:00PM every Wednesday starting January 31st, 2024. Talks are for 30 minutes - 1 hour with extra time for questions.
Where: Van Vleck B325
Who: All undergraduate and graduate students interested in algebraic geometry, abstract algebra, commutative algebra, representation theory, and related fields are welcome to attend.
Why: The purpose of this seminar is to learn algebraic geometry and commutative algebra by giving and listening to talks in a informal setting. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth. Regardless the goal of GAGS is to provide a supportive and inclusive place for all to learn more about algebraic geometry and commutative algebra.
How: If you want to get emails regarding time, place, and talk topics (which are often assigned quite last minute) add yourself to the gags mailing list: gags@g-groups.wisc.edu by sending an email to gags+subscribe@g-groups.wisc.edu. If you prefer (and are logged in under your wisc google account) the list registration page is here.
Enrollment in Math 941: The correct section to enroll for Math 941 is is with primary instructor being Dima Arinkin. If you are signed up for this section, you are expected to give a talk to get a grade.
Organizers: John Cobb, Kevin Dao, Yu (Joey) Luo.
Feedback Form for Organizers: The form is anonymous. You can find it here.
Give a talk!
We need volunteers to give talks. Beginning graduate students, e.g. first and second year students, are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material. If you would like some talk ideas, see the wish list below and the main page.
It is also expected that people enrolled in Math 941: Seminar in Algebra must give a talk to get credit.
The sign-up for Math 941: Seminar in Algebra is a section with Dima Arinkin. Please make sure you signed up for this section if you want credit.

New Wishlist as of Spring 2024
The following is a list of topics that would be good to have in a graduate algebra and algebraic geometry seminar.
- Introduction to Quiver Representations.
- The Riemann-Roch Theorem, its generalizations: Grothendieck-Riemann-Roch, Hirzebruch-Riemann-Roch, and applications.
- GAGA Theorems and how to use them.
- Cohen-Macaulay rings and schemes and variants of this type. A useful topic for those working with "mild singularities".
- Hodge Theory for the working Algebraic Geometer. What is the Hodge decomposition? What is the Hard Lefschetz Theorem? What is the statement of the Hodge conjecture? Dolbeault cohomology?
- Algebraic Curves via Hartshorne Chapter IV. What can be said projective curves of degree d and genus g? How do (did) people study algebraic curves? What are the important facts about curves a working algebraic geometer should know?
- Algebraic Suraces via Hartshorne Chapter V and Beauville's Complex Algebraic Surfaces. What does the birational classification of complex algebraic surfaces look like? How should we classify objects?
- Basics of Moduli: functor of points, representable functors, moduli of curves M_g, and why do we care?
- What is a syzygy? Compute some minimal free resolutions and tell people about how this syzygies can tell you a lot about a curve.
- Derived categories and the Fourier-Mukai Transform. Introduce derived categories and explain their importance in algebraic geometry e.g. through the Fourier-Mukai transform.
Being an audience member
The goal of GAGS is to create a safe and comfortable space inclusive of all who wish to expand their knowledge of abstract algebra, algebraic geometry, representation theory, and commutative algebra. In order to promote such an environment in addition to the standard expectations of respect/kindness all participants are asked to following the following guidelines:
- Do not speak for/over the speaker
- Ask questions appropriately
- Save lengthy questions or highly technical questions for after the talk
Talks
| Date | Speaker | Title | Abstract |
| 01-31-2024 | Kevin Dao | Setting up GAGS + A Survival Guide to Sheaf Cohomology. | Discussion about GAGS expectations + getting list of speakers.
The short talk shall be about the basics of sheaf cohomology and all about telling the audience what they need to start computing things. The goal is to prove the genus-degree formula for smooth curves in the projective plane. |
| 02-07-2024 | Boyana Martinova | ||
| 02-14-2024 | Caitlin Davis | Introduction to the Rational Normal Curve | The rational normal curve is an important example of many nice algebraic and geometric properties. I will discuss some of these properties, focusing on small concrete examples. This talk will aim to be accessible to grad students who have taken a semester or two of abstract algebra, and will not assume much (if any) algebraic geometry background. |
| 02-21-2024 | Jack Messina | Introducing Nonabelian Hodge Theory | |
