On the Torsion Function with Mixed Boundary Conditions [PDF]

Potential Analysis, 2020
AbstractLet D be a non-empty open subset of $\mathbb {R}^{m}, m\ge 2$ ℝ m , m ≥ 2 , with boundary ∂D,

Isospectral domains with mixed boundary conditions [PDF]

Journal of Physics A: Mathematical and General, 2006
We construct a series of examples of planar isospectral domains with mixed Dirichlet-Neumann boundary conditions. This is a modification of a classical problem proposed by M. Kac.

Brown-York charges with mixed boundary conditions [PDF]

Journal of High Energy Physics, 2021
Abstract We compute the Hamiltonian surface charges of gravity for a family of conservative boundary conditions, that include Dirichlet, Neumann, and York’s mixed boundary conditions defined by holding fixed the conformal induced metric and the trace of the extrinsic curvature.

Mixed Cauchy problem with lateral boundary condition for noncharacteristic degenerate hyperbolic equations

Boundary Value Problems, 2022
In this paper, in a cylindrical domain D = Ω × ( 0 , T ) $D=\Omega \times (0,T)$ with Ω ⊂ R n $\Omega \subset {R}^{n}$ , we consider a mixed Cauchy problem with a potential lateral boundary condition for the following noncharacteristic degenerated ...

Semianalytical Solutions to the Axisymmetric Free Strain Consolidation Problem of Unsaturated Soils under the Homogeneous and Mixed Boundary Conditions

Geofluids, 2022
Since the wide applicability of axisymmetric consolidation model, the axisymmetric consolidation problem of unsaturated soils has gradually become a hot issue.

Fractional Differential Equations with Mixed Boundary Conditions [PDF]

Bulletin of the Malaysian Mathematical Sciences Society, 2017
In this paper, we discuss the existence and uniqueness of solutions of a boundary value problem for a fractional differential equation of order $ \in(2,3)$, involving a general form of fractional derivative. First, we prove an equivalence between the Cauchy problem and the Volterra equation.

Magma flow through elastic-walled dikes [PDF]

, 2005
A convection–diffusion model for the averaged flow of a viscous, incompressible magma through an elastic medium is considered. The magma flows through a dike from a magma reservoir to the Earth’s surface; only changes in dike width and velocity over ...

Mixed boundary conditions and brane-string bound states [PDF]

Nuclear Physics B, 1998
In this article we consider open strings with mixed boundary conditions (a combination of Neumann and Dirichlet conditions at each end). We discuss how their end points show a $D_p$-brane with NS-NS charge, i.e. a bound state of a D-brane with a fundamental strings. We show that these branes are BPS saturated.

Surface charges in Chern-Simons gravity with T T ¯ $$ T\overline{T} $$ deformation

Journal of High Energy Physics, 2022
The T T ¯ $$ T\overline{T} $$ deformed 2D CFTs correspond to AdS3 gravity with Dirichlet boundary condition at finite cutoff or equivalently a mixed boundary condition at spatial infinity.

Laplace’s and Poisson’s Equations in a Semi-Disc under the Dirichlet-Neumann Mixed Boundary Condition

Trends in Computational and Applied Mathematics, 2023
In this work, the solution of Poisson's equation in a semi-disc under a Dirichlet boundary condition at the base and a Neumann boundary condition on the circumference is calculated.
