Algebraic K-Theory originated in the 1960's and has today grown into a vast, active branch of mathematics. It has made inroads into other areas of mathematics like Algebraic topology, Algebraic geometry and Algebraic Number Theory . After a brief introduction to the K-groups, we shall largely focus on the groups , and . The preliminaries will constitute a third of the course. We will provide various snapshots of the linkages of K-theory to some of the areas mentioned above. We shall then study the groups for a field of characteristic not 2, and its connections with the algebraic theory of quadratic forms over the field , and to the Galois cohomology groups , leading to the statement of the Milnor conjectures, now a theorem due to Voevodsky. There will be no final exam for this course. I will try to make the course as self-contained as possible, pointing to further readings as the course progresses. There will be periodic assignments which will serve as a basis for assigning a final grade.
