Boundary conditions are:

U(0)=U(1)=0

+ * - =

This is an "Euler-type" or "equipotential" equation. As chisigma said, you can try a solution of the form to get the "characteristic equation".

It is also true that the substitution t= ln(x) converts an "Euler-type" equation into an equation with constant coefficients having the same characteristic equation.
