Fundamental Green's functions are developed for the case of scalar wave
propagation in a stochastic heterogeneous medium.
employed combines an efficient derivation for Green's functions based on
algebraic transformations with the perturbation approach.
to specific heterogeneities and small randomness, the resulting expressions
for the mean value and covariance matrix are obtained in closed form and
can therefore be directly used in standard boundary integral equation
formulations for stochastic problems.
The mathematical description of heterogeneous media is a difficult
proposition and solutions are known only for very specific types of
heterogeneity within a given category of problems.
Also, natural media
invariably manifest variations that can be thought of a...
