Abstract:
In this thesis, we define some new classes of meromorphic and multivalent functions
using the techniques of convolution, subordination and generalized Carathéodory
functions. The concepts of bounded boundary rotation and bounded radius rotation are
extended. We study these new classes thoroughly and investigate several inclusion
relations, coefficient results, radius problems, integral and convolution preserving
properties. Most of these results are best possible. Various known and new results are
derived as special cases.
