Typically real harmonic functions

Abstract: We consider a class T O H of typically real harmonic functions on the unit disk that contains the class of normalized analytic and typically real functions. We also obtain some partial results about the region of univalence for this class.

“…We denote by S o Hα the subclass of S Hα consisting of u such that c −1 = 0. In [4,10,25], the typically real harmonic mappings are studied. Similar to the typically real functions of analytic functions or harmonic functions, we want to study the complex-valued kernel α−harmonic functions with real coefficients.…”

“…and the assumption, we must have |a 2 | ≤5 2 and |a 2 − b 2 | < 2. Since (2a 2 )/3 has to be a half integer by(3.2), a 2 ∈ {0, 3/2, −3/2}.It follows from the inequality |a 2 − b 2 | < 2 with b 2 = 1 2 that either a 2 = 0 or a 2 = 3 2 , since a 2 = −3/2 is not possible.…”
