SUMMARY

The discussion focuses on solving the partial differential equation (PDE) given by dG/dt=(n*s-u)(s-1)dG/ds. The recommended technique involves solving the equation \(\frac{ds}{(ns-u)(s-1)}= dt\) to find the characteristic function g(u,s) as a constant. The solution G(u, s) can be expressed as G(u, s) = F(g(u,s)), where F(t) is any differentiable function of a single variable. This method effectively utilizes the characteristics of the PDE to derive a solution.

Hi, could anyone tell me what kind of technique I should use to solve the following PDE?

dG/dt=(n*s-u)(s-1)dG/ds

Many thanks and happy new year to everyone:)

n and u are constants?

You can solve
\frac{ds}{(ns-u)(s-1)}= dt
for the "characteristic" g(u,s)= constant.

For F(t) any differentiable function of single variable, G(u, s)= F(g(u,s)) is a solution to the differential equation.
