A Hardy inequality in a twisted Dirichlet-Neumann waveguide
We consider the Laplacian in a straight strip, subject to a combination of Dirichlet and Neumann boundary conditions. We show that a switch of the respective boundary conditions leads to a Hardy inequality for the ...

Curved planar quantum wires with Dirichlet and Neumann boundary conditions.
We investigate the discrete spectrum of the Hamiltonian describing a quantum particle living in the two-dimensional curved strip. We impose the Dirichlet and Neumann boundary conditions on opposite sides of the strip. The e...

Eigenvalue inequalities for the Laplacian with mixed boundary conditions
. The eigenvalues subject to a Dirichlet boundary condition on a part of the boundary and a Neumann boundary condition on the remainder of the boundary are estimated in terms of either Dirichl...

SPECTRUM OF THE LAPLACIAN IN A NARROW CURVED STRIP WITH COMBINED DIRICHLET AND NEUMANN BOUNDARY CONDITIONS
in the plane, subject to Dirichlet boundary conditions on one of the curves and Neumann boundary conditions on the other. We derive two-term asymptotics for eigenvalues points where the ratio of the curvature radi...

Absolute continuity of the spectrum in a twisted Dirichlet-Neumann waveguide
Quantum waveguides with the shape of a planar infinite straight strip and combined Dirichlet and Neumann boundary conditions on the opposite half-lines of the boundary are considered. The absence of the point as we...

The boundary value problems for the scalar Oseen equation
We develop an explicit potential theory for the scalar Oseen equation and solve the interior and exterior Oseen Dirichlet and Oseen Neumann boundary value problems via a boundary integral equation method in spaces ...

On the discreteness of the spectra of the Dirichlet and Neumann p-biharmonic problems
We are interested in a quasilinear fourth-order boundary value problem with Dirichlet and Neumann boundary conditions. We prove that eigenvalues of both problems form increasing unbounded sequences. The first eigen...

The asymptotic behaviour of the heat equation in a twisted Dirichlet-Neumann waveguide
We consider the heat equation in a straight strip, subject to a combination of Dirichlet and Neumann boundary conditions. We show that a switch of the respective boundary conditions leads to an improvement of the d...

Higher order gamma-limits for singularly perturbed Dirichlet-Neumann problems
A mixed Dirichlet-Neumann problem is regularized with a family of singularly perturbed Neumann-Robin boundary problems, parametrized by ε > 0. Using an asymptotic development by Gamma-convergence, the asymptotic...
