Upper bound of second Hankel Determinant for subclasses of close-to-convex functions / Muhammad Fazrul Azmi
No full textAn analytic function assumes that every complex number, with possibly by one exception, infinitely often in any neighborhood of an essential singularity. That is an example of complex analysis from Picard’s great theorem. An analytic function, A, is one-to-one mapping of one region onto another region in the complex plane. The normalized analytic function is defined if function is regular and univalent in A (Goodman, 1983)
Upper bound of second Hankel determinant for subclass of close-to-convex functions / Muhammad Fazrul Azmi... [et al.]
No full textGeometric function theory is an extraordinary area of complex analysis. This area of
study is more often associated with geometric properties of analytic function such as
extremal properties, radius properties, representation theorem and coefficient bound.
Many researchers raised the interest in studying properties in different classes that have
been introduced. In this research, we focus on defining new subclasses of analytic
functions, L(a,<5,t,s) afterwards determining the upper bound of second Hankel
determinant for the selected class of function
