Subharmonic functions associated with the stationary Schrödinger operator are weak solutions of the inequality ∆u − c(x)u ≥ 0 under appropriate assumptions on the potential c. We derive for these functions analogs of several classical results on analytic and subharmonic functions such as the Phragmén-Lindelöf theorem with the precise growth rate, the(More)
