On maximal parabolic regularity for non-autonomous parabolic operators [PDF]

open access: yes, 2016
We consider linear inhomogeneous non-autonomous parabolic problems associated to sesquilinear forms, with discontinuous dependence of time. We show that for these problems, the property of maximal parabolic regularity can be extrapolated to time ...

Singular nonlinear elliptic equations in Rn

open access: yesAbstract and Applied Analysis, 1998
This paper deals with existence, uniqueness and regularity of positive generalized solutions of singular nonlinear equations of the form −Δu+a(x)u=h(x)u−γ in Rn where a,h are given, not necessarily continuous functions, and γ is a positive number.

Regular Partitions of Hypergraphs: Regularity Lemmas

open access: yesCombinatorics, Probability and Computing, 2007
Szemerédi's regularity lemma for graphs has proved to be a powerful tool with many subsequent applications. The objective of this paper is to extend the techniques developed by Nagle, Skokan, and the authors and obtain a stronger and more ‘user-friendly’ regularity lemma for hypergraphs.

After effect of perceived regularity

open access: yes, 2016
Regularity is a ubiquitous feature of the visual world. We demonstrate that regularity is an adaptable visual dimension: The perceived regularity of a pattern is reduced following adaptation to a pattern with a similar or greater degree of regularity ...

Quartic Regularity [PDF]

open access: yesVietnam Journal of Mathematics
Abstract In this paper, we propose new linearly convergent second-order methods for minimizing convex quartic polynomials. This framework is applied for designing optimization schemes, which can solve general convex problems satisfying a new condition of quartic regularity.

ON THE REGULARITY OF SLE TRACE

open access: yes, 2017
We revisit regularity of SLE trace, for all $\unicode[STIX]{x1D705}\neq 8$, and establish Besov regularity under the usual half-space capacity parametrization.

Regularity of large solutions for the compressible magnetohydrodynamic equations

open access: yesBoundary Value Problems, 2011
In this paper, we consider the initial-boundary value problem of one-dimensional compressible magnetohydrodynamics flows. The existence and continuous dependence of global solutions in H 1 have been established in Chen and Wang (Z Angew Math Phys 54, 608-

On the continuity of solutions to advection-diffusion equations with slightly super-critical divergence-free drifts

open access: yesAdvances in Nonlinear Analysis, 2014
We address the regularity of solutions to elliptic and parabolic equations of the form -Δu+b·∇u=0${- \Delta u+b\cdot \nabla u=0}$ and ut-Δu+b·∇u=0${u_t- \Delta u+b\cdot \nabla u=0}$ with divergence-free drifts b.

Global existence and regularity of solutions for active liquid crystals [PDF]

open access: yes, 2017
We study the hydrodynamics of active liquid crystals in the Beris-Edwards hydrodynamic framework with the Landau-de Gennes Q-tensor order parameter to describe liquid crystalline ordering.
