Inhomogeneous poly-scale refinement type equations and Markov operators with perturbations [PDF]

, 2015
Given measure spaces (Ω1,A1,μ1), . . . , (ΩN,AN,μN), functions φ1 : Rm×Ω1 Rm, . . . ,φN : Rm×ΩN Rm and g : Rm R, we present results on the existence of solutions f : Rm R of the inhomogeneous poly-scale refinement type equation of the form f(x) =

Quasi‐homogeneous associative functions

International Journal of Mathematics and Mathematical Sciences, Volume 21, Issue 2, Page 351-357, 1998., 1997
A triangular norm is a special kind of associative function on the closed unit interval [0, 1]. Triangular norms (or t‐norms) were introduced in the context of probabilistic metric space theory, and they have found applications also in other areas, such as fuzzy set theory.

Note on an Iterative Functional Equation

Annales Mathematicae Silesianae
We study the problem of solvability of the equation ϕ(x)=∫Ωg(w)ϕ(f(x,ω))P(dω)+F(x),\varphi \left( x \right) = \int_\Omega {g\left( w \right)} \varphi \left( {f\left( {x,\omega } \right)} \right)P\left( {d\omega } \right) + F\left( x \right), where P is ...

On Functions with Monotonic Differences

Annales Mathematicae Silesianae
Motivated by the Szostok problem on functions with monotonic differences (2005, 2007), we consider a-Wright convex functions as a generalization of Wright convex functions.

Dependency Relations Among the Shifts of a Multivariate Refinable Distribution

, 1998
. Refinable functions are an intrinsic part of subdivision schemes and wavelet constructions. The relevant properties of such functions must usually be determined from their refinement masks.

Comparing Quasi-Newton Methods for Solving Sparse Interface Problems

, 1993
We examine some quasi-Newton methods for interface problems which arise from domain decomposition methods. These interface problems are usually sparse systems of linear or non-linear equations.
