First Order Logic, Fixed Point Logic and Linear Order
The Ordered conjecture of Kolaitis and Vardi asks whether xed point logic di ers from rst order logic on every in nite class of nite ordered structures In this paper we develop the tool of bounded variable element types and illustrate its application to this and the orig inal conjectures of McColm which arose from the study of inductive de nability and in nitary logic on pro cient classes of ni...
متن کاملOn the compactness property of extensions of first-order G"{o}del logic
We study three kinds of compactness in some variants of G"{o}del logic: compactness,entailment compactness, and approximate entailment compactness.For countable first-order underlying language we use the Henkinconstruction to prove the compactness property of extensions offirst-order g logic enriched by nullary connective or the Baaz'sprojection connective. In the case of uncountable first-orde...
متن کاملA Higher Order Modal Fixed Point Logic
We present a higher order modal fixed point logic (HFL) that extends the modal μ-calculus to allow predicates on states (sets of states) to be specified using recursively defined higher order functions on predicates. The logic HFL includes negation as a first-class construct and uses a simple type system to identify the monotonic functions on which the application of fixed point operators is se...
متن کاملFirst-Order Logic vs. Fixed-Point Logic in Finite Set Theory
The ordered conjecture states that least fixed-point logic LFP is strictly more expressive than first-order logic FO on every infinite class of ordered finite structures. It has been established that either way of settling this conjecture would resolve open problems in complexity theory. In fact, this holds true even for the particular instance of the ordered conjecture on the class of BIT-stru...
متن کاملOn the fixed point of order 2
This paper deals with a new type of fixed point, i.e;"fixed point of order 2" which is introduced in a metric spaceand some results are achieved.
