We investigate warped-twisted product semi-slant submanifolds. We prove that
a warped-twisted product semi-slant submanifold of the form f2MT ×f1 Mθ with
warping function f2 on Mθ and twisting function f1 is a locally doubly warped
product, where MT
is a holomorphic and Mθ
is a slant submanifold of a globally
conformal Kaehler manifold. Then, we obtain a general inequality for the squared
norm of the second fundamental form of the doubly warped product semi-slant
submanifolds and get some results for these types of submanifolds
