partial q%fferential equations can be solved using the GaZerkin-finite element method to generate the approximating algebraic equations, and an electrical network to solve the resulting matrices. Some element configurations require the use of networks containing negative resistances which, while physically realizable, are more expensive and timeconswning to construct.

This paper presents a framework for the construction of Galerkin approximations of elliptic boundary-value problems with stochastic input data. A variational formulation is developed which allows, among others, numerical treatment by the finite element method; a theory of a posteriori error estimati
The finite-difference schemes give linear relations of the unknowns. Iterative simulations of partial differential equations are seen as iterative processes, and hence, an attempt is made to treat the points to be simulated as vertices of a graph. One way to pass through the vertices once and only o
