We introduce new subclasses S Ïƒ,s k Î», Î´, Ï† and K Ïƒ,s k Î», Î´, Ï† of analytic functions with respect to k-symmetric points defined by differential operator. Some interesting properties for theseâ€¦ (More)

Motivated by Carlson-Shaffer linear operator, we define here a new generalized linear operator. Using this operator, we define a class of analytic functions in the unit disk U. For this class, aâ€¦ (More)
