AN INTRODUCTION TO COMPUTATIONAL STOCHASTIC …

1 A N I N T RO D U C T I O N T O C O M P U TAT I O NA LS T O C H A S T I C P D E SThis book gives a comprehensive INTRODUCTION to numerical methods and anal-ysis of STOCHASTIC processes, random fields and STOCHASTIC differential equations,and offers graduate students and researchers powerful tools for understanding un-certainty quantification for risk analysis. Coverage includes traditional stochasticordinary differential equations with white noise forcing, strong and weak approx-imation and the multilevel Monte Carlo method. Later chapters apply the theoryof random fields to the numerical solution of elliptic PDEs with correlated randomdata, discuss the Monte Carlo method and introduce STOCHASTIC Galerkin finite ele-ment methods.

2 Finally, STOCHASTIC parabolic PDEs are little previous exposure to probability and statistics, theory is devel-oped in tandem with state-of-the-art COMPUTATIONAL methods through worked ex-amples, exercises, theorems and proofs. The set of MATLAB codes included (anddownloadable) allows readers to perform computations themselves and solve thetest problems discussed. Practical examples are drawn from finance, mathematicalbiology, neuroscience, fluid flow modelling and materials a professor in the Maxwell Institute, Department of Math-ematics, at Heriot-Watt University. He has worked on STOCHASTIC PDEs and ap-plications for more than ten years.

3 He is the coeditor ofStochastic Methods inNeuroscience(with C. Laing) and has organised a number of international meet-ings in the field. He has served as an Associate Editor for theSIAM Journal onScientific Computingand theSIAM/ASA Journal on Uncertainty a senior lecturer in applied mathematics and numericalanalysis at the University of Manchester. She has worked in the field of stochasticPDEs and uncertainty quantification for more than ten years. Together with TonyShardlow, she initiated the NASPDE (Numerical Analysis of STOCHASTIC PDEs)series of meetings. She has also served as an Associate Editor for theSIAM/ASAJ ournal on Uncertainty SHARDLOWhas been working in the numerical analysis group at the Uni-versity of Bath since 2012.

4 Before that, he held appointments at the universities ofManchester, Durham, Oxford and Minnesota. He completed his PhD in scientificcomputing and COMPUTATIONAL mathematics at Stanford University in in this web service Cambridge University PressCambridge University Press978-0-521-89990-1 - An INTRODUCTION to COMPUTATIONAL STOCHASTIC PdesGabriel J.
