In this paper we study the projections and some recovery problem of a finite CO-dimensional Banach spaces in terms of the projection of their complementations, more precisely we study the following problems: (1) If Y is a finite Co-dimensional subspace of a Banach space X and Z is its complementation, is for every projection P 0 from X onto Z and every > 0… (More)

We study the asymptotic distribution of eigenvalues of integral operators T k defined by kernels k which belong to Triebel-Lizorkin function space F σ pu (F τ qv) by using the factoriza-tion theorem and the Weyl numbers x n. We use the relation between Triebel-Lizorkin space F σ pu (Ω) and Besov space B τ pq (Ω) and the interpolation methods to get an… (More)
