## Abstract A back and forth condition on interpretations for those secondβorder languages without functional variables whose nonβlogical vocabulary is finite and excludes functional constants is presented. It is shown that this condition is necessary and sufficient for the interpretations to be eq
## Abstract The main purpose of this note is to characterize consistency of logic theories in propositional logic by means of topological concept. Based on the concepts of truth degree of formulas and similarity degree between formulas the concept of logic metric space has been proposed by the firs
We prove a local normal form theorem of the Gaifman type for the infinitary logic LβΟ(Q u ) Ο whose formulas involve arbitrary unary quantifiers but finite quantifier rank. We use a local Ehrenfeucht-FraΓ―ssΓ© type game similar to the one in [9]. A consequence is that every sentence of LβΟ(Q u ) Ο of
## Abstract We introduce a complete and cutβfree proof system for a sufficiently expressive fragment of Metric Temporal Logic over dense time domains in which a schema of induction is provable. So doing we extend results previously obtained by Montagna et al. to unbounded temporal operators. (Β© 200
