One faces at least three basic problems of genuine biological autonomy: (1) if biological autonomy is not physical, where does it come from? (2) Is there a room for biological causes? And (3) how to obtain a workable model of biologica ...

For suitable potentials one can treat θ as a complex variable and regard Hθ := U ∗ (θ)HU (θ) as an analytic family of operators. An easy calculation shows that if θ is continued off the real axis, the essential sp ...
