Total boundness in vector-valued F-seminormed function spaces

open access: yesLe Matematiche, 2011
We present a compactness criterion of Vitali-type in a class of vector-valued real F-seminormed spaces, which satisfy the W-property.

Infinite system of nonlinear tempered fractional order BVPs in tempered sequence spaces

open access: yesBoundary Value Problems
This paper deals with the existence results of the infinite system of tempered fractional BVPs D r ϱ , λ 0 R z j ( r ) + ψ j ( r , z ( r ) ) = 0 , 0 < r < 1 , z j ( 0 ) = 0 , 0 R D r m , λ z j ( 0 ) = 0 , b 1 z j ( 1 ) + b 2 0 R D r m , λ z j ( 1 ) = 0 ,

Measures of noncompactness in Hilbert $C^*$-modules

open access: yes
Consider a countably generated Hilbert $C^*$-module $\mathcal M$ over a $C^*$-algebra $\mathcal A$. There is a measure of noncompactness $λ$ defined, roughly as the distance from finitely generated projective submodules, which is independent of any ...
