ON NON-UNIFORM CONDITIONS GIVING WEAK NORMAL STRUCTURE

Quaestiones Mathematicae, 1995
Abstract Several non-uniform conditions sufficient for weak normal structure have recently been introduced. We show that some of these are in fact equivalent and also utilize them in applications towards a 3-space property for weak normal structure, thereby improving on earlier results.

Magnetostatic Propagation for Uniform Normally‐Magnetized Multilayer Planar Structures

AIP Conference Proceedings, 1976
Magnetostatic propagation in layered structures with magnetization in the plane and perpendicular to the direction of propagation has been studied theoretically and experimentally. Problems in device application of this geometry include low power saturation levels and limited delay times for reasonable film sizes.

On a generalized modulus of convexity and uniform normal structure

Acta Mathematica Scientia, 2007
Abstract In this article, the authors study a generalized modulus of convexity, δα)(ɛ). Certain related geometrical properties of this modulus are analyzed. Their main result is that Banach space X has uniform normal structure if there exists ɛ, 0 ≤ ɛ ≤ 1, such that δ(α) (1 + ɛ) > (1-α) ɛ.
