Multiscale Model Reduction

​Eric Chung is a Professor in the Department of Mathematics and an Outstanding Fellow of the Faculty of Science at the Chinese University of Hong Kong. His research focuses on numerical discretizations of partial differential equations and the development of computational multiscale methods for challenging applications.Yalchin Efendiev is a Professor in the Department of Mathematics at the Texas A&M University.Thomas Y. Hou is the Charles Lee Powell Professor of Applied and Computational Mathematics at the California Institute of Technology. His research focuses on multiscale analysis and computation, fluid interface problems, and singularity formation of 3D Euler and Navier-Stokes equations.

“This is a self-contained presentation of the multiscale finite element methods. Each chapter starts with motivating examples and a description of the methods. This book provides a good starting point for those interested in multiscale finite element methods. I recommend this book to any graduate students and scholars seeking to solve multiscale problems with finite element methods.” (Huadong Gao, Mathematical Reviews, January, 2025) “The book is a nice survey of multiscale model reduction and is suitable for researchers in other areas who wish to approach this domain and also for specialists in the field as a general reference.” (Nicolae Cîndea, zbMATH 1543.65001, 2024)
