Abstract :In this study,a new class C_{Σ}^{p,q}insert ignore into journalissuearticles values(α); of analytic and bi-concave functions were presented in the open unit disc. The coefficients estimates on the first two Taylor-Maclaurin coefficients |a₂| and |a₃| were found for functions belonging to this class.
