Accuracy, Robustness, and Efficiency of the Linear Boundary Condition for the Black-Scholes Equations

Discrete Dynamics in Nature and Society, 2015
We briefly review and investigate the performance of various boundary conditions such as Dirichlet, Neumann, linear, and partial differential equation boundary conditions for the numerical solutions of the Black-Scholes partial differential equation.

Existence and non-existence results for a nonlinear heat equation

Electronic Journal of Differential Equations, 2007
In this study, we consider the nonlinear heat equation $$displaylines{ u_{t}(x,t) = Delta u(x,t) + u(x,t)^p quad hbox{in } Omega imes (0,T),cr Bu(x,t) = 0 quad hbox{on } partialOmega imes (0,T),cr u(x,0) = u_0(x) quad hbox{in } Omega,}$$ with ...

Symmetry theorems via the continuous steiner symmetrization

Electronic Journal of Differential Equations, 2000
Using a new approach due to F. Brock called the Steiner symmetrization, we show first that if $u$ is a solution of an overdetermined problem in the divergence form satisfying the Neumann and non-constant Dirichlet boundary conditions, then $Omega$ is an ...

Non-steady magneto-hydrodynamics-heat system with joule and buoyancy effects under mixed boundary conditions

Electronic Journal of Differential Equations
This article concerns the non-steady magneto-hydro-dynamics (MHD) heat system with Joule and buoyancy effects under mixed boundary conditions. The boundary conditions for fluids can include the stick, total pressure, vorticity, total stress conditions ...
