Аннотация:It is well known that the least possible type under the order ρ from the class of entire functions with upper root density 1 (for the exponent ρ) is 1/(eρ). The author proves that if all the roots of entire functions lie on one ray, then the situation is different: the least type for such a class on the set of orders (1,+∞) ∖ ℕ is distinct from zero and is bounded above.
