From: hsue@midway.uchicago.edu (yung chang hsueh) Newsgroups: sci.math.research Subject: $200 for solutions of OEDs Date: Thu, 16 Sep 1993 22:10:56 GMT I will Award $200 for the analytic solutions to the following system of ODE: 0= ay -1 + y' 0= -ay + 0.5 b^2 z^2 + cz + z' 0= 0.5 y^2 - fy + 0.5 g w^2 + h w + w' where y, z, w are functions of x. a, b, c, f, g ,h are constants . boundary conditions: y(0)=z(0)=w(0)=0 Note: to my understanding the solution can be expressed in Confluent Hypergeometric Functions. The key issue is to find out transformations that turn the second and third equations into confluent hypergeometric equations.
