In [13], Kleene formulated a truth-notion called "readability" for formulas of intuitionistic number theory(1). David Nelson(2) showed that every number-theoretic formula deducible in the intuitionistic predicate calculus(3) (stated by means of schemata, without proposition or predicate variables) from realizable number-theoretic formulas is realizable. In particular, then, every formula in the...

This study aims to determine the extent of mathematical literacy skills by applying Group Investigation type cooperative learning model. Mathematics achievement in Indonesia is still low, as seen PISA and TIMSS surveys, one private junior high schools Malang mathematics using conventional learning. The research method qualitative with a descriptive approach nine students subject. results showed...

We show how PVS-style predicate subtyping can be simulated in HOL using predicate sets, and explain how to perform subtype checking using this model. We illustrate some applications of this to specification and verification in HOL, and also demonstrate some limits of the approach. Finally we report on the effectiveness of a subtype checker used as a condition prover in a contextual rewriter.
