*Başlık/Title: *ON A NEW LOCALLY CONFORMAL DEFORMATION ON ALMOST CONTACT
METRIC STRUCTURES

*Özet/Abstract:*  In this talk,we introduce a new locally conformal
deformation that preserves almost contact metric structures. By means of
deformation change, we define locally transversally conformal Kenmotsu
manifolds, for which we derive fundamental equations and characterizations.
We also give a rigitidy result for locally transversally conformal Kenmotsu
manifolds. Moreover, we present an explicit example to support our
theoretical results.
