Title: Introduction to Boolean Algebras, Ultrafilters, and


We will introduce Boolean algebras, the usual partial ordering on a
Boolean algebra, and infinitary Boolean operations.  We then will cover
the basics of filters, ultrafilters, ultraproducts, ending with some
relevant basic facts which will be background for a later Logic Seminar
lecture by Christopher Griffin.  This material can be found in
Koppelberg's "Handbook of Boolean Algebra", or Jech's "Set Theory"
