Let X be a real Banach space with dual X∗ and suppose that F:X→X∗. We give a characterisation of the property that F is locally proper and establish its stability under compact perturbation. Modifying an recent result of ours, we prove that any

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

A trace inequality for the generalized Riesz potentials Iα(x) is established in spaces Lp(x) defined on spaces of homogeneous type. The results are new even in the case of Euclidean spaces. As a corollary a criterion for a two-weighted inequality in

The theory of Lebesgue and Sobolev spaces with variable integrability is experiencing a steady expansion, and is the subject of much vigorous research by functional analysts, function-space analysts and specialists in nonlinear analysis. These spaces

New scales of grand variable exponent Hajlasz–Sobolev and Holder spaces are introduced. Embeddings between these spaces are established under the log-Holder continuity condition on exponent functions of spaces. Spaces are defined, generally speakin

We compute the precise value of the measure of noncompactness of Sobolev embeddings $W_0^{1,p}(D)\hookrightarrow L^p(D)$, $p\in(1,\infty)$, on strip-like domains $D$ of the form $\mathbb{R}^k\times\prod\limits_{i=1}^{n-k}(a_i,b_i)$. We show that such

Let Ω be a bounded open subset of R n with a mild regularity property, let m ∈ N and p ∈ ( 1 , ∞ ) , and let W m , p ( Ω ) be the usual Sobolev space of order m based on L p ( Ω ) ; the closure in W m , p ( Ω ) of the smooth functions with
