On changing cofinality of partially ordered sets
It is shown that under GCH every poset preserves its cofinality in any cofinality preserving extension. On the other hand, starting with measurable cardinals, a model with a part...

A Genuinely High Order Total Variation Diminishing Scheme for One-Dimensional Scalar Conservation Laws
It is well known that finite difference or finite volume total variation diminishing (TVD) schemes solving one-dimensional scalar conservation laws degenerate to first order accura...

Positive periodic solutions for higher order functional difference equations
In this paper, we apply a fixed point theorem to obtain sufficient conditions for the existence of positive periodic solutions for two classes of higher-order functional differenc...

Definability of second order generalized quantifiers
We study definability of second-order generalized quantifiers. We show that the question whether a second-order generalized quantifier Q1 is definable in terms of another quantifie...
