Apr 20, 2017 at 20:41 comment added Seyhmus Güngören @george2079 otherwise the search goes into complex numbers and it takes alot ot time. So this is the only reason, and normally I would not put them.
Apr 20, 2017 at 20:40 comment added george2079 why are you taking Abs in g0,g1 ? The result no longer satisfies the implicit relation of course.
Apr 20, 2017 at 11:07 comment added Mauricio Fernández Just as a remark: do you know or have you checked, that the implicit equations for $g_0$ and $g_1$ admit solutions for all $y \in (-\infty,\infty)$? I mean, if this is not the case, then the integration over all real values is impossible to performe, since the integral does not exist. Simple example: f[y_] := PDF[NormalDistribution[-1, 1], y] eq1 = g - (f[y]*Exp[g])^(1/1); N@Solve[eq1 == 0 && Element[y, Reals], g, Reals] Plot[Evaluate[g /. %], {y, -2, 2}] Resolve[ForAll[y, Exists[g, eq1 == 0]], Reals] Resolve[ForAll[y, y < -2 || y > -4/10, Exists[g, eq1 == 0]], Reals]
