Third Hankel determinant for the class of analytic functions defined by Mathieu-type series related to a petal-shaped domain

UDC 517.5 We introduce a new subclass of analytic functions based on the Mathieu-type series related to a petal-shaped domain. We investigate the bounds of the initial coefficient estimates, the Fekete–Szegö inequality, and the Hankel determinant of order two and three.
