Local Reflexivity and Duality for Subspace Approximation Schemes
Daniel Akech Thiong
We address a structural gap in the quantitative theory of operator approximation by investigating how subspace approximation schemes interact with local reflexivity. Recent literat…

Schauder's Theorem and s-Numbers
Asuman Guven Aksoy, Daniel Akech Thiong
Motivated by the well known theorem of Schauder, we study the relationship between various s-numbers of an operator T and its adjoint T* between Banach spaces.
