Multiple Solutions of Dirichlet Problem for Semilinear Elliptic Equations at Resonance [PDF]
Multiplicity results are obtained, by the minimax method, for solutions of the Dirichlet problem for semilinear elliptic equations at resonance with unbounded and nonautonomous non-linearities.

The Poisson equation in homogeneous Sobolev spaces
We consider Poisson′s equation in an n‐dimensional exterior domain G(n ≥ 2) with a sufficiently smooth boundary. We prove that for external forces and boundary values given in certain Lq(G)‐spaces there exists a solution in the homogeneous Sobolev space S2,q(G), containing functions being local in Lq(G) and having second‐order derivatives in Lq(G ...

Weierstraß-Institut für Angewandte Analysis und Stochastik Interpolation for function spaces related to mixed boundary value problems Dedicated to Helga Rothkirch [PDF]
Interpolation theorems are proved for Sobolev spaces of functions on nonsmooth domains with vanishing trace on a part of the boundary.

A finite‐dimensional reduction method for slightly supercritical elliptic problems
We describe a finite‐dimensional reduction method to find solutions for a class of slightly supercritical elliptic problems. A suitable truncation argument allows us to work in the usual Sobolev space even in the presence of supercritical nonlinearities: we modify the supercritical term in such a way to have subcritical approximating problems; for ...

Examples of non-Dini domains with large singular sets
Let uu be a nontrivial harmonic function in a domain D⊂RdD\subset {{\mathbb{R}}}^{d}, which vanishes on an open set of the boundary. In a recent article, we showed that if DD is a C1{C}^{1}-Dini domain, then, within the open set, the singular set of uu ...

A functionally-analytic method for modelling axial-symmetric flows of ideal fluid
We consider axial-symmetric stationary flows of the ideal incompressible fluid as an important case of potential solenoid fields. We use an integral expression of the Stokes flow function via the corresponding complex analytic function for solving a ...

Capillary Schwarz symmetrization in the half-space
In this article, we introduce a notion of capillary Schwarz symmetrization in the half-space. It can be viewed as the counterpart of the classical Schwarz symmetrization in the framework of capillary problem in the half-space.

An elliptic problem with critical exponent and positive Hardy potential
We give the existence result and the vanishing order of the solution in 0 for the following equation: −Δu(x) + (μ/|x|2)u(x) = λu(x) + u2*−1(x), where x ∈ B1, μ > 0, and the potential μ/|x|2 − λ is positive in B1.

Logistic equation with the p‐Laplacian and constant yield harvesting
We consider the positive solutions of a quasilinear elliptic equation with p‐Laplacian, logistic‐type growth rate function, and a constant yield harvesting. We use sub‐super‐solution methods to prove the existence of a maximal positive solution when the harvesting rate is under a certain positive constant.
