A family of singular ordinary differential equations of the third order with an integral boundary condition
(Springer, 2018-12)
We establish in this paper the equivalence between a Volterra integral equation of the second kind and a singular ordinary differential equation of the third order with two initial conditions and an integral boundary ...
A note on the controllability for the wave equation in nonsmooth plane domains
(Elsevier B.V., 2006-01-01)
We study exact boundary controllability for a two-dimensional wave equation in a region which is an angular sector of a circle or an angular sector of an annular region. The control, of Neumann type, acts on the curved ...

Instability of asymptotically anti-de Sitter black holes under Robin conditions at the timelike boundary
(American Physical Society, 2017-11-15)
The static region outside the event horizon of an asymptotically anti-de Sitter black hole has a conformal timelike boundary I on which boundary conditions have to be imposed for the evolution of linear fields from initial ...
Topological methods for a nonlinear elliptic system with nonlinear boundary conditions
(Inderscience Publishers, 2009-09)
A nonlinear elliptic second order system with a nonlinear boundary condition is studied. We prove an existence result under a Hartman type condition. Moreover, assuming appropriate conditions of Nirenberg type, we prove ...

Neumann Casimir effect: A singular boundary-interaction approach
(Elsevier Science, 2010-05)
Dirichlet boundary conditions on a surface can be imposed on a scalar field, by coupling it quadratically to a δ-like potential, the strength of which tends to infinity. Neumann conditions, on the other hand, require the ...
Boussinesq system with non-homogeneous boundary conditions
(2016)
A classical stationary Boussinesq system with non-homogeneous Dirichlet boundary conditions in a bounded domain Omega subset of R-3 is considered in this paper; included is the case of a possibly disconnected boundary. We ...
