Some Compactness Criteria for Weak Solutions of Time Fractional PDEs [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2017
The Aubin-Lions lemma and its variants play crucial roles for the existence of weak solutions of nonlinear evolutionary PDEs. In this paper, we aim to develop some compactness criteria that are analogies of the Aubin--Lions lemma for the existence of ...

Compact Fusion [PDF]

open access: yesElectronic Workshops in Computing, 2006
There are many advantages to writing functional programs in a compositional style, such as clarity and modularity. However, the intermediate data structures produced may mean that the resulting program is inefficient in terms of space. These may be removed using deforestation techniques, but whether the space performance is actually improved depends ...

Existence of solutions for critical Choquard equations via the concentration-compactness method [PDF]

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2017
In this paper, we consider the nonlinear Choquard equation $$-\Delta u + V(x)u = \left( {\int_{{\open R}^N} {\displaystyle{{G(u)} \over { \vert x-y \vert ^\mu }}} \,{\rm d}y} \right)g(u)\quad {\rm in}\;{\open R}^N, $$ where 0 < μ < N, N ⩾ 3, g(u) is of ...

Compactness and lower semicontinuity in $GSBD$ [PDF]

open access: yesJournal of the European Mathematical Society (Print), 2018
In this paper, we prove a compactness and semicontinuity result in $GSBD$ for sequences with bounded Griffith energy. This generalises classical results in $(G)SBV$ by Ambrosio and $SBD$ by Bellettini-Coscia-Dal Maso.

Statistical compactness

open access: yesTopology and its Applications, 2023
Organising the relevant literature and by letting statistical convergence play the main role in the theory of compactness, a variant of compactness called statistical compactness has been achieved. As in case of sequential compactness, one point statistical compactification is studied to some extent too.

The compactness of spatial structure in Chinese cities: measurement, clustering patterns and influencing factors

open access: yes, 2020
Rapid urbanization in China has led to an excessive urban expansion of built-up areas, which makes quantitative research on compact city important. We adopted density and the degree of mixed land use to measure the compactness of 160 Chinese cities ...

Singular compactness and definability for $$\Sigma $$-cotorsion and Gorenstein modules [PDF]

open access: yes, 2018
We introduce a general version of the singular compactness theorem which makes it possible to show that being a $$\Sigma $$-cotorsion module is a property of the complete theory of the module.

Objective constraints of figural goodness [PDF]

open access: yesPsihologija, 2002
The effects of uniformity, compactness and symmetry on pattern goodness estimates were evaluated in three experiments. Ss were asked to choose the pattern which looks the best in respect to other patterns from given set.
