Abstract: The 𝛢 subclasses π‘†βˆ—(𝜏, πœ†) and πΆβˆ—(𝜏, πœ†), as well as the class of analytic and univalent functions of the form β„Ž(𝑀) = 𝑀 βˆ’ Ξ£ |𝑒𝑖 |𝑀𝑖 βˆžπ‘– =2 , were studied. Sharp coefficients, distortion, as well as a function expression formula in π‘†βˆ—(𝜏, πœ†) are determined, as well as expression formulae for functions in πΆβˆ—(𝜏, πœ†). In addition, convex linear combination over arithmetic average, the classes π‘†βˆ—(𝜏, πœ†) and πΆβˆ—(𝜏, πœ†) are proved to be closed
