New sufficient conditions for starlike and convex functions
Nishiwaki, Junichi; Owa, Shigeyoshi (Işık University Press, 2014)Let A be the class of analytic functions f(z) in the open unit disc. Applying the subordination, some sufficient conditions for starlikeness and convexity are discussed. -
Notes on certain harmonic starlike mappings
Yavuz Duman, Emel; Owa, Shigeyoshi (Işık University Press, 2014)Complex-valued harmonic functions that are univalent and sense-preserving in the unit disk D can be written in the form f = h + ¯g, where h and g are analytic in D. We give some inequalities for normalized harmonic functions ...
