The connections between quasi-Assouad dimension and tangents are studied. We apply these results to the calculation of for a class planar self-affine sets. also show that sets with decreasing gaps have 0 or 1 exhibit an example set in plane whose is smaller than its projection onto \(x\)-axis, showing may increase under Lipschitz mappings. Moreover, closed sets, we Hausdorff upper bound quasi-l...

For a T3.s-ordered space, certain families of maps are designated as "defining families." For each such defining family we construct the smallest T=-ordered compactification such that each member of the family can be extended to the compactification space. Each defining family also generates a quasi-uniformity on the space whose bicompletion produces the same T=-ordered

We show that for even quasi-concave objective functions the worst-case distribution, with respect to a family of unimodal distributions, of a stochastic programming problem is a uniform distribution. This extends the so-called “Uniformity Principle” of Barmish and Lagoa (1997) where the objective function is the indicator function of a convex symmetric set.

We investigate the emission from confined excitons in the structure of a single-monolayer-thick quasi-two-dimensional (quasi-2D) InxGa1-xN layer inserted in GaN matrix. This quasi-2D InGaN layer was successfully achieved by molecular beam epitaxy (MBE), and an excellent in-plane uniformity in this layer was confirmed by cathodoluminescence mapping study. The carrier dynamics have also been inve...

We prove uniform Ancona—Gouëzel—Lalley inequalities for an extension by a hyperbolic group G of Markov map which allows to deduce that the visual boundary and Martin are Hölder equivalent. As application, we identify set minimal δ-conformal measures regular cover convex-cocompact CAT(-1)-manifold with covering group, provided this is hyperbolic. In setting, uniformity minimal, densities in sens...

We introduce and discuss several types of ?-?-contractive mappings on quasi-metric spaces. obtain some fixed point theorems in this setting present suitable examples to show the validity our approach results. Finally, we give a characterization doubly Hausdorff right K-sequentially complete spaces terms type having point.

Generalising Nachbin's theory of ``topology and order'', in this paper we   continue the study of quantale-enriched categories equipped with a compact   Hausdorff topology. We compare these $V$-categorical compact Hausdorff spaces   with ultrafilter-quantale-enriched categories, and show that the presence of a   compact Hausdorff topology guarantees Cauchy completeness and (suitably   defined) ...

<p style='text-indent:20px;'>We discuss the existence and uniqueness of mild solutions for a class quasi-linear fractional integro-differential equations with impulsive conditions via Hausdorff measures noncompactness fixed point theory in Banach space. Mild solution controllability is discussed two particular cases.</p>

We introduce and study the notions of a strongly completable and of a strongly complete quasi-uniform space. A quasi-uniform space (X,U) is said to be strongly complete if every Cauchy filter (in the sense of Sieber and Pervin) clusters in the uniform space (X,U ∨ U−1). An interesting motivation for the study of this notion of completeness is the fact, proved here, that the quasi-uniformity ind...
