Inhomogeneous infinity Laplace equation
Advances in Mathematics, 2008 We present the theory of the viscosity solutions of the inhomogeneous infinity Laplace equation ∂xiu∂xju∂xixj2u=f in domains in Rn. We show existence and uniqueness of a viscosity solution of the Dirichlet problem under the intrinsic condition f does not

The Laplace equation Δu = 0 occurs frequently in applied sciences, in particular in the study of the steady state phenomena. Its solutions are called harmonic functions. For instance, the equilibrium position of a perfectly elastic membrane is a harmonic function as it is the velocity potential of a homogeneous fluid. Also, the steady state temperature

The Laplace operator acting on a function u(x) = u(x1,...,x n ) of class C2 in a region Ω is defined by $$\Delta = \sum\limits_{{k = 1}}^{n} {D_{k}^{2}}$$ (1.1) For \(u,\upsilon \in {C^{2}}\left( {\overline \Omega } \right)\) we have (see Chapter 3, (4.8), (4.9)) Green’s identities.

Laplace's Equation and Network Flows
Operations Research, 1967This paper shows that the problem of Laplace's equation can be formulated as a minimum cost network flow problem with quadratic cost. Then an algorithm for solving quadratic cost network flow problems can be modified to solve the standard Laplace's equation.

Let Ω be a domain in ℝ n and u a C 2(Ω) function. The Laplacian of u, denoted ⊿u, is defined by $$\Delta u = \sum\limits_{i = 1}^n {{D_u}u = div} Du.$$ (2.1)

In Chapter 4 we have discussed the PDEs that control the heat flow in two and three dimensional spaces given by $$ \begin{gathered} u_t= \bar k(u_{xx}+ u_{yy} ), \hfill \\ u_t= \bar k(u_{xx}+ u_{yy}+ u_{zz} ), \hfill \\ \end{gathered} $$ (7.1) respectively, where \( \bar k \) is the thermal diffusivity.
