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.

In this paper we study the stability of the single internal spike solution of a simplified Gierer-Meinhardt' system of equations in one space dimension. The linearization around this spike consists of a selfadjoint differential operator plus a non-lo

We determine the exact dependence on \(\theta,q,p\) of the constants in the equivalence theorem for the real interpolation method \((A_0,A_1)_{\theta,q}\) with pairs of \(p\)-normed spaces.

Sharp reiteration theorems for the K-interpolation method in limiting cases are proved using two-sided estimates of the K-functional. As an application, sharp mapping properties of the Riesz potential are derived in a limiting case. © 2011 WILEY-VCH

We prove optimal embeddings in the subcritical case of the inhomogeneous Sobolev spaces built-up over function spaces in Rn with K−monotone and rearrangement invariant norm into another rearrangement invariant function spaces. The investigation is
