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 ,

On bifurcation points of strongly condensing operators

open access: yesНаучный вестник МГТУ ГА, 2016
Two conditions equivalent to complete continuity of Frechet derivative at a point and the asymptotic derivative in the case of their existence are given. Theorem of M.A. Krasnosel’skii on asymptotic bifurcation points for completely con-tinuous fields to

ON OPERATORS WITH THE SPHERICAL PROPERTY

open access: yesНаучный вестник МГТУ ГА, 2016
Properties of continuous positively homogeneous operators of degree via various functions (e.g. measures of noncompactness) on all bounded subsets of a Banach space are studied.
