Completeness of sparse, almost integer, and finite local complexity sequences of translates in Lp(R)$L^p(\mathbb {R})$

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract A real sequence Λ={λn}n=1∞$\Lambda = \lbrace \lambda _n\rbrace _{n=1}^\infty$ is called p$p$‐generating if there exists a function g$g$ whose translates {g(x−λn)}n=1∞$\lbrace g(x-\lambda _n)\rbrace _{n=1}^\infty$ span the space Lp(R)$L^p(\mathbb {R})$.

Regulated functions with values in Banach space

Mathematica Bohemica, 2019
A function \(f:[a,b]\to X\) of one real variable \(t\in [a,b]\) with values in a Banach space \(X\) is said to be regulated if at each point \(t\in [a,b]\) both the right limit \(f(t+)\) and the left limit \(f(t-)\) exist with the convention \(f(a-)=f(a)\), \(f(b+)=f(b)\). This paper gives an overview of topological properties of the space \(G([a,b];X)\

Extrapolation of Compactness on Banach Function Spaces

Journal of Fourier Analysis and Applications
AbstractWe prove an extrapolation of compactness theorem for operators on Banach function spaces satisfying certain convexity and concavity conditions. In particular, we show that the boundedness of an operator T in the weighted Lebesgue scale and the compactness of T in the unweighted Lebesgue scale yields compactness of T on a very general class of ...
