We give some results of various kinds concerning Î»-spirallike functions of complex order and Î»-Robertson functions of complex order in the unit disc U = {z : |z| < 1}. They represent extensions andâ€¦ (More)

Let H denote the class of functions f(z) = z+âˆ‘âˆžk=2akzk which are analytic in the unit disc âˆ† = {z : |z| < 1}. In this paper, we introduce the class MÎ» Î±[A,B] of functions f âˆˆ H with f(z)f â€²(z)/z â‰ 0,â€¦ (More)

A complex valued function f = u+ iv defined in a domain D âŠ‚ C, is harmonic in D, if u and v are real harmonic. Such functions can be represented as f(z) = h(z) + g(z), where h an g are analytic in D.â€¦ (More)
