Series: Penn State Logic Seminar Date: Tuesday, August 28, 2001 Time: 2:30 - 3:45 PM Place: 306 Boucke Building Speaker: Natasha L. Dobrinen, Mathematics, Penn State Title: Introduction to von Neumann's Problem Concerning Measurable Boolean Algebras, part 1 Abstract: Von Neumann conjectured that every countably complete Boolean algebra which satisfies the countable chain condition and the weak (omega,omega)-distributive law carries a strictly positive, countably additive measure. This talk will cover some of the background and history concerning von Neumann's problem.
