Mathematics of Operations Research, Vol. 12, No. 4 (Nov., 1987), pp. 678-699 (22 pages) We consider generalizations of the steepest descent algorithm for solving asymmetric systems of equations. We ...

We prove a nonlinear steepest descent theorem for Riemann-Hilbert problems with Carleson jump contours and jump matrices of low regularity and slow decay. We illustrate the theorem by deriving the ...
