We introduce a weighted reproducing kernel Hilbert space which is based on Walsh functions. The worst-case error for integration in this space is studied, especially with regard to (t,m,s)-nets.

An embedding theorem for a weighted space of Sobolev type and correct solvability of the Sturm-Liouville equation [PDF]
summary:We consider the weighted space $W_1^{(2)}(\mathbb R,q)$ of Sobolev type $$ W_1^{(2)}(\mathbb R,q)=\left \{y\in A_{\rm loc}^{(1)}(\mathbb R)\colon \|y''\|_{L_1(\mathbb R)}+\|qy\|_{L_1(\mathbb R)}0\colon \inf _{x\in \mathbb R}\int _{x-a}^{x+a} q ...

Existence of Solutions for Degenerate Elliptic Problems in Weighted Sobolev Space
This paper is devoted to the study of the existence of solutions to a general elliptic problem Au+g(x,u,∇u)=f-divF, with f∈L1(Ω) and F∈∏i=1NLp'(Ω,ωi*), where A is a Leray-Lions operator from a weighted Sobolev space into its dual and g(x,s,ξ) is a ...

Elliptic Equations in Weighted Sobolev Spaces on Unbounded Domains [PDF]
We study in this paper a class of second‐order linear elliptic equations in weighted Sobolev spaces on unbounded domains of ℝn, n ≥ 3. We obtain an a priori bound, and a regularity result from which we deduce a uniqueness theorem.

Existence of solutions for quasilinear parabolic equations at resonance
In this article, we show the existence of nontrivial solutions for a class of quasilinear parabolic differential equations. To obtain the solution in a weighted Sobolev space, we use the Galerkin method, Brouwer's theorem, and a compact Sobolev-type ...

Hardy-Sobolev inequalities and weighted capacities in metric spaces
Let $\Omega$ be an open set in a metric measure space $X$. Our main result gives an equivalence between the validity of a weighted Hardy–Sobolev inequality in $\Omega$ and quasiadditivity of a weighted capacity with respect to Whitney covers of $\Omega$.

Embeddings of a Multi-Weighted Anisotropic Sobolev Type Space
Parameters such as various integral and differential characteristics of functions, smoothness properties of regions and their boundaries, as well as many classes of weight functions cause complex relationships and embedding conditions for multi-weighted

Jumping nonlinearities and weighted Sobolev spaces
Working in a weighted Sobolev space, a new result involving jumping nonlinearities for a semilinear elliptic boundary value problem in a bounded domain in RN is established. The nonlinear part of the equation is assumed to grow at most linearly and to be
