Abstract

In this article, we find a condition on a so that if 1+αzzf'(z)/f(z) < 1+Az/1+Bz; then zF'(z)/F(z) < 1+sin (z); where F(z) = γ+1/zβ ∫z0 tγ-1 f(t)dt; is the well-known Bernardi integral operator. We also study the case zF'(z)/F(z) < cos(z): Some similar implications are also discussed for both functions. [ABSTRACT FROM AUTHOR]
