H\"older estimates for parabolic operators on domains with rough boundary [PDF]
, 2015 We investigate linear parabolic, second-order boundary value problems with mixed boundary conditions on rough domains. Assuming only boundedness and ellipticity on the coefficient function and very mild conditions on the geometry of the domain, including

General Holmstedt’s Formulae for the K-Functional
Journal of Function Spaces, 2017 Explicit formulae for the K-functional for the general couple ((A0,A1)Φ0,(A0,A1)Φ1), where (A0,A1) is a compatible couple of quasi-normed spaces, are proved. As a consequence, the corresponding reiteration theorems are derived.

Limits of higher-order Besov spaces and sharp reiteration theorems
Journal of Functional Analysis, 2005 The authors compute the limits of higher-order Besov norms and derive the sharp constants for certain forms of the Sobolev embedding theorem using interpolation methods. Their result extends, to higher-order spaces, the work by \textit{H. Brézis, J. Bourgain, P. Mironescu} in [Optimal control and partial differential equations.

On the Infinite in Mereology with Plural Quantification [PDF]
, 2010 In Lewis reconstructs set theory using mereology and plural quantification (MPQ). In his recontruction he assumes from the beginning that there is an infinite plurality of atoms, whose size is equivalent to that of the set theoretical universe.

Interpolation of Ces{\`a}ro sequence and function spaces
, 2012 The interpolation property of Ces{\`a}ro sequence and function spaces is investigated. It is shown that $Ces_p(I)$ is an interpolation space between $Ces_{p_0}(I)$ and $Ces_{p_1}(I)$ for $1 < p_0 < p_1 \leq \infty$ and $1/p = (1 - \theta)/p_0 + \theta ...

Sharp Estimates of the Embedding Constants for Besov Spaces [PDF]
, 2006 Sharp estimates are obtained for the rates of blow up of the norms of embeddings of Besov spaces in Lorentz spaces as the parameters approach critical values.Sharp estimates are obtained for the rates of blow up of the norms of embeddings of Besov spaces

Interpolation orbit functorsand reiteration theorems
Bulletin des Sciences Mathématiques, 2000 In the paper under review, the author uses certain ideals operators to study interpolation orbit functors from couples of weighted \(\ell^p\) or \(c_0\) spaces to the class of regular finite dimensional couples. The author shows that the abstract \(J\)-method of interpolation has an orbital description which is used to study interpolation orbit ...

Real interpolation of Sobolev spaces
, 2008 We prove that $W^{1}_{p}$ is an interpolation space between $W^{1}_{p_{1}}$ and $W^{1}_{p_{2}}$ for $p>q_{0}$ and $1\leq p_{1}

Characterization of interpolation between Grand, small or classical Lebesgue spaces
, 2017 In this paper, we show that the interpolation spaces between Grand, small or classical Lebesgue are so called Lorentz-Zygmund spaces or more generally $G\Gamma$-spaces. As a direct consequence of our results any Lorentz-Zygmund space $L^{a,r}({\rm Log}\,
