Abstrakt: The logarithmic coeffcients of univalent functions play an important role in different estimates in the theory of univalent functions. In this paper, due to the significant importance of the study of these coeffcients, we find the upper bounds for some expressions associated with the logarithmic coeffcients of functions that belong to some classes defined by using the subordination. Moreover, we get the best upper bounds for the logarithmic coeffcients of some subclasses of analytic functions defined and studied in many earlier papers. [ABSTRACT FROM AUTHOR]
