General Holmstedt’s Formulae for the K-Functional [PDF]
Journal of Function Spaces, 2017 Explicit formulae for the K-functional for the general couple ((A0,A1)Φ0,(A0,A1)Φ1), where (A0,A1) is a compatible couple of quasi-normed spaces, are proved. As a consequence, the corresponding reiteration theorems are derived.

The Convergence Rate for a K-Functional in Learning Theory [PDF]
Journal of Inequalities and Applications, 2010 It is known that in the field of learning theory based on reproducing kernel Hilbert spaces the upper bounds estimate for a K-functional is needed.

On a Functional Equation Associated with (a,k)-Regularized Resolvent Families
Abstract and Applied Analysis, 2012 Let a∈Lloc1(ℝ+) and k∈C(ℝ+) be given. In this paper, we study the functional equation R(s)(a*R)(t)-(a*R)(s)R(t)=k(s)(a*R)(t)-k(t)(a*R)(s), for bounded operator valued functions R(t) defined on the positive real line ℝ+.

A generalized version of Holmstedt’s formula for the $K$-functional
Colloquium MathematicumLet $(A_0, A_1)$ be a compatible couple of quasi-normed spaces, and let $Φ_0$ and $Φ_1$ be two general parameters of $K$-interpolation method. We compute $K$-functional for the couple $((A_0,A_1)_{Φ_0}, (A_0, A_1)_{Φ_1})$ in terms of $K$-functional for the couple $(A_0, A_1)$.

Asymptotic behaviour of the solution of a functional-differential equation [PDF]
, 1984 The asymptotic behaviour as t→∞ of the solution of the functional- differential equation y'(t) = -y(t/k), with y(0) = 1 and k > 1 , is derived from an integral representation by the method of steepest descents.

On the algebra of $A^k$-functions [PDF]
Mathematica Bohemica, 2006 Summary: For a domain \(\Omega \subset {\mathbb C}^n\) let \(H(\Omega )\) be the holomorphic functions on \(\Omega \) and for any \(k\in \mathbb N\) let \(A^k(\Omega )=H(\Omega )\cap C^k(\overline {\Omega })\). Denote by \({\mathcal A}_D^k(\Omega )\) the set of functions \(f\: \Omega \to [0,\infty )\) with the property that there exists a sequence of ...
