  Subharmonic functions associated with the stationary Schrodinger operator are
its weak subsolutions under appropriate assumptions on the potential of the
operator. We prove for these functions analogs of several classical results on
analytic and subharmonic functions, such as the Phragmen-Lindelof theorem with
the precise growth rate, the Blaschke theorem on bounded analytic functions,
the Carleman formula, the Hayman-Azarin theorem on asymptotic behavior of
special subharmonic functions in many-dimensional cones.
