Working Seminar on Etale Cohomology

Regular time and place: TBA. Organizational meeting: Friday January 6, 2pm, in MATH 126.
Organizers: Uriya First , Julia Gordon.


The goal is to study Etale Cohomology, with the hope to understand the definition of l-adic cohomology groups, Grothendieck's sheaf-function dictionary, Lefschetz fixed point formula, and perhaps the sketch of the idea of the proof of Weil conjectures by Deligne (though this is unlikely to be included in the seminar itself). l-adic cohomology has wide applications in algebraic geometry, arithmetic geometry, number theory, and representation theory of finite and p-adic groups (eg., character theory of finite groups of Lie type is stated entirely in these terms), and is also important for the formulation of the geometric Langlands conjectures.
