For an algebraic curve V in C k × C n it is investigated when it satisfies the Phragmén-Lindelöf condition PL(ω) of evolution in certain classes of ultradifferentiable functions. Necessary as well as sufficient conditions are obtained which lead to a complete characterization for curves in C × C n .
The aim of this paper is to prove the following theorem of the PHRAGMEN-LINDE-LOF type. ## Theorem. Let f ( z ) be analytic in the angular domain and for some p E (0, + -) satistifis the following conditions: a) there exists the boundary function f [ r e q ) ( k i i x l ( 2 a ) ) I ~L p (0, +-) s
We consider the function f ( z ) analytic in the half plane Q+ = { z : Im z -0) and continuous in its closure. Theorems of the PHEAGMJ~N-LINDELOF type are characterized by assuming growth restrictions for If(z)l in the closure of @+, which are sufficient for i t to be bounded or at most of exponenti
