Abstract
The Nevanlinna-type spaces
$N_\varphi $
of analytic functions on the disk in the complex plane generated by strongly convex functions
$\varphi $
in the sense of Rudin are studied. We show for some special class of strongly convex functions asymptotic bounds on the growth of the Taylor coefficients of a function in
$N_\varphi $
and use these to characterize the coefficient multipliers from
$N_\varphi $
into the Hardy spaces
$H^p$
with
$0
. As a by-product, we prove a representation of continuous linear functionals on
$N_\varphi $
.

The Nagoya Mathematical Journal is published quarterly. Since its formation in 1950 by a group led by Tadashi Nakayama, the journal has endeavoured to publish original research papers of the highest quality and of general interest, covering a broad range of pure mathematics. The journal is owned by Foundation Nagoya Mathematical Journal, which uses the proceeds from the journal to support mathematics worldwide.
