The discussion focuses on solving an ordinary differential equation (ODE) with a regular singular point at x=0 using series methods. Participants suggest starting with a power series representation, y=∑c_nx^n, and substituting it into the differential equation. Due to the regular singular point, the Method of Frobenius is recommended, proposing the use of a series of the form y=∑c_nx^(n+r). This approach allows for the determination of coefficients that satisfy the ODE. The conversation emphasizes the applicability of this method to ODEs with similar singular characteristics.

Start by letting $y=\sum\limits_{n=0}^{\infty}c_nx^n$ and taking the appropriate derivatives and plugging them into the DE.

Actually, since $x=0$ is a regular singular point of this DE, you're going to have to use the Method of Frobenius. Try
$$y=\sum_{n=0}^{\infty}c_{n}x^{n+r}.$$
