Multiplication operators in spaces of entire functions of finite order and operators of convolution type. (English. Russian original) Zbl 0565.47018
Math. USSR, Sb. 48, 499-520 (1984); translation from Mat. Sb., Nov. Ser. 120(162), No. 4, 505-527 (1983).
This is a continuation of the author’s considerable and exhaustive work on convolution epimorphisms in complex analysis [see Dokl. Akad. Nauk. SSSR 217, 18-19 (1974; Zbl 0314.47023); Mat. Zametki 16, 415-422 (1974; Zbl 0331.47026); Mat. Zametki 15, 787-796 (1974; Zbl 0314.46050)]. In the present paper the author considers a continuous operation of multiplication by a particular function a(z), acting on certain spaces of entire functions of finite order and determines the condition for it to have a closed range. This is equivalent to determining the conditions under which the adjoint operator is a convolution epimorphism.
