Quadratic forms: This course will study quadratic forms from an algebraic and arithmetic point of view. It is intended for a wide range of students, ranging from advanced undergraduates who have had Math 502/503 or the equivalent, to grad students who might already have taken the more usual version of Math 620 (class field theory). Topics will include quadratic spaces, Witt groups and rings, quaternion algebras, Brauer group, quadratic forms over local and global fields, Hasse-Minkowski, and field invariants.
schedule: Mon and Wed, 1:30-3pm in DRL 4C8.
- Textbook: T.Y. Lam, Introduction to Quadratic forms over Fields, Graduate Studies in Mathematics, vol. 67, AMS, 2005.
- Course structure: The class will meet twice weekly. There will be regular homework assignments to be handed in. Those students who are registered in 620 or 702 will also make oral presentations, either individually or in groups. Those who are registered in 520 can also choose to make such a presentation for extra credit.

Student presentations: Presentations can be made individually, or in groups of
two or three, depending on the scope of the presentation. Individual presentations
should be for 20-30 minutes; group presentations should be about twice that length. Presentations
can be made on suggested topics or on other approved
topics. Presentations will be made at the beginning of class, beginning November 21,
until the last day of class.
Topics and dates need to be reserved and approved in advance. To request or reserve a topic, as well as to reserve a time, email
