## Elliptic systems and quasiconformal mappingsThis monograph, which includes new results, is concerned with elliptic systems of first-order partial differential equations in the plane, in which quasiconformal mappings play a crucial role, and whose solutions are generalized analytic functions of the second kind, denoted here (?,?)-solutions. This is a brilliant translation of the German edition published in the Tuebner-text series in 1982. |
