Download or read book A Survey of Some Applications of Probability and Stochastic Control Theory to Finite Difference Methods for Degenerate Elliptic and Parabolic Equations written by Harold J. Kushner and published by . This book was released on 1974 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finite difference methods for degenerate linear and (certain) non-linear elliptic and parabolic equations are analyzed from a probabilistic point of view, and probabilistic methods to show convergence to the correct weak or strong sense solution. The techniques generalize results in numerical analysis, and the probabilistic approach allows some additional physical insight to be brought to bear on the problem of selecting suitable approximations and methods of solution. The equations which are discussed all have probabilistic interpretations.
