Popis: In the present paper we introduce a new class of analytic functions f in the open unit disk normalized by f(0) = f′(0)−1 = 0, associated with exponential functions. The aim of the present paper is to investigate the third-order Hankel determinant H3(1) for this function class and obtain the upper bound of the determinant H3(1).
