“Sometimes” and “Not Never” Revisited
... that in both casesthe underlying time structures are branching). He then compares the expressive power of linear time and branching time logic and finds them incomparable. On the basis of his comparison and other arguments, he concludes that, although branching time logic is suitable for reasoning a ...

OPERATORS WITH A GIVEN PART OF THE NUMERICAL RANGE 1
... More information about numerical ranges can be found in [1] and [2], for instance. An interesting application of this notion in the study of other properties of linear operators can be find in [7]. The aim of this paper is to study sets of operators with a prescribed part of the numerical range. Mor ...

The classical Łoś-Tarski theorem states that every first-order sentence preserved under extensions is equivalent to an existential sentence. We show that there is no elementary bound on the length of the existential sentence in terms of the ...

Completeness in modal logic - Lund University Publications
... I shall try to summarize the “guide to intensional semantics” as briefly as possible. The article starts by introducing two new concepts: width and depth. Width and depth are measures of how many systems some type of semantics, e. g. relational semantics, makes complete. The width of some semantics ...
