Welcome to Math 250B: Algebra
Aside from containing many subfields in its own right, algebra is of
fundamental importance in many other areas of mathematics, including
number theory, algebraic geometry, algebraic topology, and representation
theory. We will begin with the subject of tensor products, which are
important in all of the above fields, as well as in differential geometry
(and by extension, general relativity). We will then move on to the basics
of representation theory, and finally we will cover the theory of
algebraic field extensions.
I will post notes here to supplement Lang as seems appropriate.
