DESCRIPTION:We may think of propositional formulas
  as schemas for formulas of a first-order language
 . The question which then naturally arises is, "Wh
 at schemas are valid in a given theory?" De Jongh'
 s theorem settles this question for HA. Since then
 , mostly extensions of HA have been considered in 
 this context. This talk will deal with much weaker
  theories of equality instead.    For abstracts an
 d more information, see http://www.math.uu.nl/peop
