Abstract

Entire functionsf(z), zC 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 ɛ-net inR n, then such f(z) are bounded on all ofR n (for e-nets in the case of sufficiently small σ). It is shown that if E is close in a certain sense either to a relatively dense subset ofR n, or to an ε-net, then f(z) cannot increase fast alongR n. Similar estimates are established for integral metrics.
