Interpolation inequalities between Sobolev and Morrey-Campanato spaces: A common gateway to concentration-compactness and Gagliardo-Nirenberg interpolation inequalities [PDF]

open access: yes, 2013
We prove interpolation estimates between Morrey-Campanato spaces and Sobolev spaces. These estimates give in particular concentration-compactness inequalities in the translation-invariant and in the translation- and dilation-invariant case.

Compact bilinear commutators: the weighted case [PDF]

open access: yes, 2015
Commutators of bilinear Calderón-Zygmund operators and multiplication by functions in a certain subspace of the space of functions of bounded mean oscillation are shown to be compact on appropriate products of weighted Lebesgue spaces.Simons ...

Stability and boundedness of regular solutions for a Sisko flow in an infinite annular porous space

open access: yesResults in Physics, 2023
The present article is intended to study the boundedness of solutions for an unsteady non-Newtonian flow, whose strain–stress relationship is provided by the Sisko fluid model.

Detecting spatial patterns with the cumulant function. Part II: An application to El Nino [PDF]

open access: yes, 2007
The spatial coherence of a measured variable (e.g. temperature or pressure) is often studied to determine the regions where this variable varies the most or to find teleconnections, i.e. correlations between specific regions.

Some unsolved problems on meromorphic functions of uniformly bounded characteristic

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
The family UBC(R) of meromorphic functions of uniformly bounded characteristic in a Rieman surface R is defined in terms of the Shimizu-Ahlfors characteristic function.

Asymptotic Profile for Diffusion Wave Terms of the Compressible Navier–Stokes–Korteweg System

open access: yesMathematics, 2021
The asymptotic profile for diffusion wave terms of solutions to the compressible Navier–Stokes–Korteweg system is studied on R2. The diffusion wave with time-decay estimate was studied by Hoff and Zumbrun (1995, 1997), Kobayashi and Shibata (2002), and ...

A conditional regularity result for p-harmonic flows [PDF]

open access: yes, 2015
We prove an $\varepsilon$-regularity result for a wide class of parabolic systems $$ u_t-\text{div}\big(|\nabla u|^{p-2}\nabla u) = B(u, \nabla u) $$ with the right hand side $B$ growing like $|\nabla u|^p$.

On Global Well-Posedness of the Lagrangian Averaged Euler Equations [PDF]

open access: yes, 2006
We study the global well-posedness of the Lagrangian averaged Euler equations in three dimensions. We show that a necessary and sufficient condition for the global existence is that the bounded mean oscillation of the stream function is integrable in ...

BMO and the John-Nirenberg Inequality on Measure Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2020
We study the space BMO𝒢 (𝕏) in the general setting of a measure space 𝕏 with a fixed collection 𝒢 of measurable sets of positive and finite measure, consisting of functions of bounded mean oscillation on sets in 𝒢.
