摘要：
In the first part of this work we present several new geometric properties of analytic functions by applying the differential subordination. In addition, several results in the geometric functions theory pointed out. In the second part we find upper bounds for coefficients of functions in class B-Sigma(q,mu)(beta, lambda, h) which is defined by fractional q-calculus operators.
