Some classes of order α for second-order differential inequalities
Hitoshi Shiraishi, Kazuo Kuroki, Shigeyoshi Owa
For analytic functions f(z) in the open unit disk U with f(0)=f'(0)-1=0, S. S. Miller and P. T. Mocanu (Integral Transform. Spec. Funct. 19(2008)) have considered some sufficient p…
New extensions for a theorem by Mocanu
Hitoshi Shiraishi, Shigeyoshi Owa
For analytic functions f(z) in the open unit disk U with f(0)=f'(0)-1=f"(0)=0, P. T. Mocanu (Mathematica (Cluj), 42(2000)) has considered some sufficient arguments of f'(z)+zf"(z)…
Sufficient conditions for strongly Carathéodory functions
Hitoshi Shiraishi, Shigeyoshi Owa, H. M. Srivastava
Applying the subordination principle for analytic functions in the open unit disk U, I. H. Kim and N. E. Cho (Comput. Math. Appl. 59(2010), 2067-2073) considered some sufficient co…
Starlikeness problems for certain analytic functions concerned with subordinations
Hitoshi Shiraishi, Shigeyoshi Owa, Toshio Hayami +2
Let A_n be the class of functions f(z) which are analytic in the open unit disk U} with f(0)=0, f'(0)=1, f"(0)=f"'(0)=...=f^{(n)}=0 and f^{(n+1)}\neq0. Applying the results due to…
An application of Miller and Mocanu lemma
Hitoshi Shiraishi, Shigeyoshi Owa
Let H[a_0,n] be the class of functions f(z)=a_0+a_nz^n+...which are analytic in the open unit disk U}. For f(z) in H[a_0,n], S. S. Miller and P. T. Mocanu (J. Math. Anal. Appl. 65(…
Properties of certain analytic functions associated with two boundary points
Hitoshi Shiraishi, Shigeyoshi Owa
For analytic functions f(z) in the closed unit disk \bar{U}, two boundary points z_1 and z_2 such that α= (f'(z_1)+f'(z_2))/2 in f'(U) are considered. The object of the present pap…
