The goal of the seminar is a quick introduction to algebraic $K$-theory with
applications in algebraic geometry and algebra. We plan to consider several approaches
to algebraic $K$-groups, mainly in the context of exact categories, and also to analyze
concepts and constructions in algebraic geometry related to algebraic $K$-theory. The
apotheosis of the seminar should be a detailed study of a proof of the famous
Merkuryev-Suslin theorem which relates Milnor $K$-groups and Brauer groups of fields.
Talks will be given mainly by undergraduate and graduate students participating
in the seminar. As for preliminaries, familiarity with algebra and algebraic geometry,
homotopy theory, category theory, and a little homological algebra will be required.
