From the reviews:pEven I, who know very little about partial differential equations and related mathematics, recognize the name of S.L. Sobolev (1908-1989) as one of the most influential contributors to the field in the 20th century. This book is the first volume of his a ~selected worksa (TM) a ] . There is no question that all good research libraries will want to have a copy of this one. (Fernando Q. GouvAaa, Math DL, October, 2006)S.L. Sobolev (1908a 1989) was a great mathematician of the twentieth century. His selected works included in this volume laid the foundations for intensive development of the modern theory of partial differential equations and equations of mathematical physics, and they were a gold mine for new directions of functional analysis and computational mathematics.pThe topics covered in this volume include Soboleva (TM)s fundamental works on equations of mathematical physics, computational mathematics, and cubature formulas. Some of the articles are generally unknown to mathematicians because they were published in journals that are difficult to access.
