Exact Null Controllability of a One-Dimensional Wave Equation with a Mixed Boundary

Mathematics, 2023
In this paper, exact null controllability of one-dimensional wave equations in non-cylindrical domains was discussed. It is different from past papers, as we consider boundary conditions for more complex cases.

Study of properties of solutions for quasilinear parabolic systems

MATEC Web of Conferences, 2016
In this paper, we concern with degenerate and quasilinear parabolic systems not in divergence form with null Dirichlet boundary conditions and positive initial conditions. The local existence and uniqueness of classical solution are proved.

Accurate energy spectrum for double-well potential: periodic basis

, 2010
We present a variational study of employing the trigonometric basis functions satisfying periodic boundary condition for the accurate calculation of eigenvalues and eigenfunctions of quartic double-well oscillators.

Singular SPDEs in domains with boundaries [PDF]

, 2018
We study spaces of modelled distributions with singular behaviour near the boundary of a domain that, in the context of the theory of regularity structures, allow one to give robust solution theories for singular stochastic PDEs with boundary conditions.

Numerical Reconstruction of the Source in Dynamical Boundary Condition of Laplace’s Equation

Axioms
In this work, we consider Cauchy-type problems for Laplace’s equation with a dynamical boundary condition on a part of the domain boundary. We construct a discrete-in-time, meshless method for solving two inverse problems for recovering the space–time ...

A Computational Model for q-Bernstein Quasi-Minimal Bézier Surface

Journal of Mathematics, 2022
A computational model is presented to find the q-Bernstein quasi-minimal Bézier surfaces as the extremal of Dirichlet functional, and the Bézier surfaces are used quite frequently in the literature of computer science for computer graphics and the ...

On a waveguide with frequently alternating boundary conditions: homogenized Neumann condition

, 2010
We consider a waveguide modeled by the Laplacian in a straight planar strip. The Dirichlet boundary condition is taken on the upper boundary, while on the lower boundary we impose periodically alternating Dirichlet and Neumann condition assuming the ...

Stability analysis for impulsive stochastic fuzzy p-Laplace dynamic equations under Neumann or Dirichlet boundary condition

Boundary Value Problems, 2013
Under Neumann or Dirichlet boundary conditions, the stability of a class of delayed impulsive Markovian jumping stochastic fuzzy p-Laplace partial differential equations (PDEs) is considered.
