This third edition of "Generalized Functions" expands the treatment of fundamental concepts and theoretical background material and delineates connections to a variety of applications in mathematical physics, elasticity, wave propagation, magnetohydrodynamics, linear systems, probability and statistics, optimal control problems in economics, and more. In applying the powerful tools of generalized functions to better serve the needs of physicists, engineers, and applied mathematicians, this work is quite distinct from other books on the subject.</P>

From the Reviewers:</P>

"Kanwals book is a worthy member of this company [Gelfand and Shilov, Semanian, Friedman, Jones, and Barros-Neto]. Its strength lies in the application to classical physics.[it presents] a wealth of applications that cannot be found in any other single sourceKanwal has written a valuable book accessible to first-year graduate students in physics and engineering."</P>

"The advantage of this text is in carefully gathered examples explaining how to use corresponding properties. Even the standard material connecting with partial and ordinary differential equations is rewritten in modern terminology."</P>
