| Sandwich-type results for a class of functions defined by a generalized differential operator |
| Priyabrat Gochhayat |
Abstract By making use of a generalized differential operator a new class of non-Bazilevič functions is introduced. Differential sandwich-type theorem for the above class is investigated. Relevant connections of the results, which are presented in this paper, with various other known results are also pointed out.
