Özet
We introduce and investigate two new subclasses N-Sigma(delta,mu)(n,alpha,lambda) and N-Sigma(delta,mu)(n,beta,lambda) of analytic and bi-univalent functions in the open unit disk U. For functions belonging to these classes, we obtain estimates on the first two Taylor-Maclaurin coefficients vertical bar a(2)vertical bar and vertical bar a(3)vertical bar.
