Introduction to algebraic groups (Daniel Allcock, Texas)

We will develop the basic structure of algebraic groups over an
algebraically closed field of any characteristic.  Emphasis will be on
explicit constructions and descriptions of objects rather than
abstract theory.  Depending on time and interest, we may also look at
what happens over a field which is not algebraically closed.  Students
should be comfortable with varieties and their basic properties (e.g.,
what's good about proper maps, how dimensions of fibers of maps
behave) but need no previous background in algebraic groups.  Lie
group background would be useful (for motivating various
constructions) but is not required.
