On the connection of the first-order functional calculus with $\aleph_0}$ propositional calculus.

A First-Order Calculus Based on Propositional BDDs

Proof Search for the First-Order Connection Calculus in Maude

This paper develops a rewriting logic specification of the connection method for first-order logic, implemented in Maude. The connection method is a goal-directed proof procedure that requires a careful control over clause copies. The specification separates the inference rule layer from the rule application layer, and implements the latter at Maude’s meta-level. This allows us to develop and c...

The Completeness of the First-Order Functional Calculus

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

On 2 nd Order Intuitionistic Propositional Calculus with Full Comprehension

(x not free in A, HPC is Heyting's predicate calculus) for the class of Kripke models of constant domains. See G6rnemann [1] for an algebraic completeness proof and Gabbay I-2] for other details. The proof of undecidability uses the same method introduced in Gabbay [3, 4] and used to obtain undecidability results for a large class of intuitionistic theories. Although some versions of the monadi...
