摘要：

In this present work, subclasses of multivalent functions of complex order associated with simple logistic sigmoid activation function and Bernoulli Lemniscate were investigated. Early few coefficient bounds, relevant connection to Fekete-Szego inequalities and second Hankel determinant for the two classes M-L(p, lambda, b, Phi(m,n)) and G(L)(p, lambda, b, Phi(m,n)) were obtained. Our results are new in this direction and give birth to many corollaries.
