For some reason
\begin{axiom}
seriesSolve(-1+(1-2*x)*y(x)-(1-4*x)*D(y(x),x)=0, y, x = 0, [1])
\end{axiom}
fails. We need to expose 'UnivariateTaylorSeriesODESolver' first:
\begin{axiom}
)expose UnivariateTaylorSeriesODESolver
seriesSolve(-1+(1-2*x)*y(x)-(1-4*x)*D(y(x),x)=0, y, x = 0, [1])
\end{axiom}
Furthermore, the documentation of 'seriesSolve' is not quite clear to me. Why
does::
seriesSolve(-1+(1-2*x)*y(x)+x*(1-4*x)*D(y(x),x)=0, y, x = 0, [1])
fail - it should give the Catalan numbers.
