Abstract: | Entire functionsf(z), z C
n
, of exponential type at most a and bounded on subsets E of the real hyperplane, are investigated. It is known that if E is relatively dense with respect to the Lebesgue measure or it is an -net inR
n
, then such f(z) are bounded on all ofR
n
(for e-nets in the case of sufficiently small ). It is shown that if E is close in a certain sense either to a relatively dense subset ofR
n
, or to an -net, then f(z) cannot increase fast alongR
n
. Similar estimates are established for integral metrics.Translated from Teoriya Funktsii, Funktsional'nyi Analiz i Ikh Prilozheniya, No. 50, pp. 74–76, 1988. |
