In this present paper, a new generalized class ℛp,q from the family of function with bounded turning was introduced by using p,q - derivative operator. Our aim for this class is to find out the upper bound of third- and fourth-order Hankel determinant. Moreover, the upper bounds for two-fold and three-fold symmetric functions for this class are also obtained.
