Student seminar

Weighted projective spaces

We will discuss weighted projective spaces (and weighted projective varieties), and their relationship to stacks.

See also the description page for more information.

ANAGRAMS is an acronym for Antwerp Algebraic Geometry, Rings and More Seminar.
As the silly name indicates, it is a (graduate student) seminar on topics related to the research areas that the algebra and geometry group of the University of Antwerp (and Brussels, and Hasselt) specialises in: noncommutative algebra, algebraic geometry, noncommutative geometry, quadratic forms, ...
The goal is to learn things, not present new results.
Room G.006, Campus Middelheim, University of Antwerp
Wednesday afternoons, at 13h00.
The lectures are given by PhD students (or postdocs). The intended audience consists of interested Master and PhD students and postdocs.
Each session of talks takes 2 hours (this is not set in stone). One person gives a 2-hour talk, there could be two 1-hour talks, or several short talks, depending on the subject. Talks are done in English.
The seminar will mostly consist of series of lectures on a single subject. The actual number may vary depending on the subject.
