A First Course in Fractional Sobolev Spaces [PDF]

open access: yesGraduate Studies in Mathematics, 2023
This book provides a gentle introduction to fractional Sobolev spaces, which play a central role in the calculus of variations, partial differential equations, and harmonic analysis. The first part deals with fractional Sobolev spaces of one variable. It

On fractional Orlicz–Sobolev spaces [PDF]

open access: yesAnalysis and Mathematical Physics, 2021
AbstractSome recent results on the theory of fractional Orlicz–Sobolev spaces are surveyed. They concern Sobolev type embeddings for these spaces with an optimal Orlicz target, related Hardy type inequalities, and criteria for compact embeddings.

Transition Threshold for the 3D Couette Flow in Sobolev Space [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2018
In this paper, we study the transition threshold of the 3D Couette flow in Sobolev space at high Reynolds number Re. It was proved that if the initial velocity v0 satisfies ∥v0−y,0,0∥H2≤c0Re−1 for some c0 > 0 independent of Re, then the solution of the ...

Basic results of fractional Orlicz-Sobolev space and applications to non-local problems [PDF]

open access: yesTopological Methods in Nonlinear Analysis, 2019
In this paper, we study the interplay between Orlicz-Sobolev spaces $L^{M}$ and $W^{1,M}$ and fractional Sobolev spaces $W^{s,p}$. More precisely, we give some qualitative properties of the new fractional Orlicz-Sobolev space $W^{s,M}$, where $s\in (0,1)$

On anisotropic Sobolev spaces [PDF]

open access: yesCommunications in Contemporary Mathematics, 2019
We investigate two types of characterizations for anisotropic Sobolev and BV spaces. In particular, we establish anisotropic versions of the Bourgain–Brezis–Mironescu formula, including the magnetic case both for Sobolev and BV functions.

Embedding theorems in the fractional Orlicz-Sobolev space and applications to non-local problems [PDF]

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2019
In the present paper, we deal with a new continuous and compact embedding theorems for the fractional Orlicz-Sobolev spaces, also, we study the existence of infinitely many nontrivial solutions for a class of non-local fractional Orlicz-Sobolev ...

Topology and Sobolev Spaces [PDF]

open access: yesJournal of Functional Analysis, 2000
AbstractConsider the Sobolev class W1, p(M, N) where M and N are compact manifolds. We present some sufficient conditions which guarantee that W1, p(M, N) is path-connected. We also discuss cases where W1, p(M, N) admits more than one component. There are still a number of open problems, especially concerning the values of p where a change in homotopy ...

Inclusion of Hajłasz – Sobolev class Mpα(X) into  the space of continuous functions in the critical case

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
Let (X, d, µ) be a doubling metric measure space with doubling dimension γ, i. e. for any balls B(x, R) and B(x, r), r < R, following inequality holds µ(B(x, R)) ≤ aµ (R/r)γµ(B(x, r)) for some positive constants γ and aµ.

Existence of Sobolev regular solutions for the incompressible flow of liquid crystals in three dimensions

open access: yesAIMS Mathematics, 2022
This paper considers a simplified three dimensional Ericksen-Leslie System for nematic liquid crystal flows in the unbounded domain $ \Omega: = \mathbb R^+\times \mathbb R^2 $ or the smooth bounded domain $ \Omega $.
