## An Introduction to Fronts in Random Media (Google eBook)This book gives a user friendly tutorial to Fronts in Random Media, an interdisciplinary research topic, to senior undergraduates and graduate students the mathematical sciences and engineering. The topics concerns both deterministic and probabilistic techniques. The approach taken uses elementary methods to introduce ideas and motivate results where possible. It takes a step by step approach, with exercises, allowing the reader to build up tools to use in research. |
