520    In this famous monograph, a distinguished mathematician 
       presents an innovative approach to classical boundary 
       value problems--one that may be used by mathematicians as 
       well as by theoreticians in mechanics. The approach is 
       based on a number of geometric properties of conformal and
       quasi-conformal mappings and employs the general basic 
       scheme for solution of variational problems first 
       suggested by Hilbert and developed by Tonnelli. The first 
       two chapters cover variational principles of the theory of
       conformal mapping and behavior of a conformal 
       transformation on the boundary. Chapters 3 and 4 explore 
       hydrodynamic applications and quasiconformal mappings, and
       the final two chapters address linear systems and the 
       simplest classes of non-linear systems. Mathematicians 
       will take particular interest in the method of the proof 
       of the existence and uniqueness theorems as well as the 
       general theory of quasi-conformal mappings. Theoreticians 
       in mechanics will find the approximate formulas for 
       conformal and quasi-conformal.
