 where the contributions $A$ and $B$ depend on $\psi$ again making the whole equation non-linear, and further may also be complex thus defining a non-unitary evolution.
-The $A$ and $B$ still include, through $\psi'$ and $\psi''$, the full wave function $\Psi$ on the whole configuration space, so this is not yet an autonomous evolution equation for the conditional wave function. But there is actually a way how to eliminate $\Psi$ and give separate evolution equations for the potentials if only in the form of an infinite [[potential network]].

+If the same treatment is //vice versa// employed for the subsystem $Y$, taking the Bohmian trajectory $x = X(t)$ to accomodate for influences of the subsystem $X$, the resulting approximation scheme is called "Bohmian Double Semi-Quantum (BDSQ)" approximation in [(:cite:cwf:norsen2016)].
