Sobolev Space On Riemannian Manifolds [PDF]

open access: yes, 2019
The main aim of this thesis is to study the theory of Sobolev spaces on Riemannian manifolds. This thesis is divided into three parts, 1st we will learn Riemannian Geometry then Sobolev space on R n at last we will define Sobolev space on Riemannian ...

Wavelets in Sobolev space over local fields of positive characteristics

open access: yes, 2018
The Sobolev space over local fields [Formula: see text] is defined. A multiresolution analysis for the Sobolev space is developed. Orthonormal wavelets with respect to these space are constructed and an example is also presented.

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

On Compressible Fluid Flows of Forchheimer‐Type in Rotating Heterogeneous Porous Media

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We study the dynamics of compressible fluids in rotating heterogeneous porous media. The fluid flow is of Forchheimer‐type and is subject to a mixed mass and volumetric flux boundary condition. The governing equations are reduced to a nonlinear partial differential equation for the pseudo‐pressure.

An estimate of the Hopf degree of fractional Sobolev mappings

open access: yes, 2020
We estimate the Hopf degree for smooth maps f from S^4n−1 to S^2n in the fractional Sobolev space. Namely we show that for s∈[1−1/(4n),1], |deg_H(f)|≲[f]^4ns_W^s,4n−1/s. Our argument is based on the Whitehead integral formula and commutator estimates for

Fractional Maximal Functions in Metric Measure Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2013
We study the mapping properties of fractional maximal operators in Sobolev and Campanato spaces in metric measure spaces. We show that, under certain restrictions on the underlying metric measure space, fractional maximal operators improve the Sobolev ...

Remarks on the Maximal Regularity for Parabolic Boundary Value Problems With Inhomogeneous Data

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Inspired by Ogawa‐Shimizu and Chen‐Liang‐Tsai on the second and first order derivative estimates of solutions of the heat equation in the upper half space with boundary data in homogeneous Besov spaces, we extend the estimates to any order of derivatives, including fractional derivatives.
