Abstract: | We consider functions which are subfunctions with respect to the differential operator
|
(1) |
and are doubly periodic in ℂ. These functions play an important role in describing the asymptotic behavior of entire and
subharmonic functions of finite order 7, Ch. 3]. In studying their properties, we are led to problems concerning the uniqueness
of Martin functions and the critical value for the parameter ρ in the homogeneous boundary problem for the operatorL
ρ in a domain on the torus.
