George C. Hsiao received a bachelor's degree in Civil Engineering from  National Taiwan University, a master's degree from Carnegie Institute of Technology in the same field,  and a doctorate degree in Mathematics  from Carnegie Mellon University. He is now the Carl J. Rees Professor of Mathematics Emeritus at the University of Delaware from which he retired in September 2012 after 43 years on the faculty of the Department of Mathematical Sciences. His primary research interests are integral equations and partial differential equations with their applications in mathematical physics and continuum mechanics.Wolfgang L. Wendland, now Professor Emeritus at the University Stuttgart was studying mechanical engineering and mathematics at the Technical University Berlin and became Full Professor for Mathematics 1970-1986 at the TU Darmstadt and 1986-2005 at the University Stuttgart. His research interests are in Applied Mathematics with emphasis on partial differential equations and integral equations as well as approximation and numerical methods with applications to continuum mechanics of flow and elasticity problems.Both authors are well known for their fundamental work on boundary integral equations and related topics.

“This second edition also expands the area of applicability of boundary integral equations … . The authors are outstanding and well known researchers in the mathematical foundations of numerical methods, mainly the boundary element methods, for solving various boundary integral equations. The multitude of their original results is the basis of this impressive volume which, however, requires a fairly high level of mathematical knowledge in order to be useful.” (Calin Ioan Gheorghiu, zbMATH 1477.65007, 2022)
