I've been wrestling this wildebeast for a looong time.
Need to find the exact critical value for y0 in the following equation:
y = Sqrt(Pi)/2 * Erf[t/Sqrt(2)] *E(t^2/2) - t - y0*Et^2/2
The "critical point" which I'm looking for is the point which separates solutions which behave in quite different ways (i.e. unbounded negatively vs. positively)...
I believe the point I'm looking for is - Sqrt(Pi)/2, but can't solve for it...
