Professor Patricia Blanchette, “Models and Consistency in Geometry and Logic”

October 5, 2012
All Day
347 University Hall

Patricia Blanchette is an Associate Professor at the University of Notre Dame.

Abstract: In what sense does a model really show the “consistency,” in any intuitive sense, of the things modeled?  This talk investigates this question by looking at some of the issues raised in a debate over consistency-proofs in geometry at the beginning of the 20th century.  Authors discussed include Frege, Hilbert, Veblen, and others.
