ω-Connected Continua and Jones' K Function

Proceedings of the American Mathematical Society, 1984
A continuum X is \(\omega\)-connected if for every pair of points x, y of X, there exists an irreducible subcontinuum of X from x to y that is decomposable. If \(A\subset X\) then K(A) is the intersection of all subcontinua of X that contain A in their interiors. The main theorem shows that if X is an \(\omega\)-connected continuum and H is a connected

Refraction of the k function at spherical surfaces

Journal of the Optical Society of America A, 1995
The k function arises in obtaining the general solution of the eikonal equation for a homogeneous, isotropic medium and describes the shape and the structure of individual wave fronts in a wave-front train as well as the associated caustic surface. The effect that refraction by a spherical refracting surface has on this k function is examined.

Directional K- Functionals Claudia Cottin

Results in Mathematics, 1993
When considering approximation of continuous periodic functions f: Rd → R by blending-type approximants which depend on directions ξ1,…,ξν ∈ Rd directional moduli of smoothness (1) are appropriate measures of smoothness of /. In this paper, we introduce equivalent directional K- functionals.

Generalized Modulus of Smoothness and K-functional.

Communications on Applied Nonlinear Analysis
Many articles introduced about direct and inverse theorems interims of ordinary modulus of smoothness andK-functional. Here we shall define a generalized modulus of smoothness andK-functional, then we prove they are equivalent.
