𝜂-RICCI SOLITONS ON KENMOTSU MANIFOLDS
Eyasmin, Sabina,Chowdhury, Partha Roy,Baishya, Kanak Kanti The Honam Mathematical Society 2018 호남수학학술지 Vol.40 No.2
The object of the present paper is to study the Kenmotsu manifolds which metric tensor is ${\eta}$-Ricci soliton. We bring out curvature conditions for which Ricci solitons in Kenmotsu manifolds are sometimes shrinking or expanding and some other times steady.

The object of the present paper is to study the Ken- motsu manifolds which metric tensor is □-Ricci soliton. We bring out curvature conditions for which Ricci solitons in Kenmotsu man- ifolds are sometimes shrinking or expanding and some other times steady.
INVARIANT SUBMANIFOLDS OF (LCS)<sub>n</sub>-MANIFOLDS ADMITTING CERTAIN CONDITIONS
( Sabina Eyasmin ),( Kanak Kanti Baishya ) 호남수학회 2020 호남수학학술지 Vol.42 No.4
The object of the present paper is to study the invariant submanifolds of (LCS)n-manifolds. We study generalized quasiconformally semi-parallel and 2-semiparallel invariant submanifolds of (LCS)n-manifolds and showed their existence by a non-trivial example. Among other it is shown that an invariant submanifold of a (LCS)n-manifold is totally geodesic if the second fundamental form is any one of (i) symmetric, (ii) recurrent, (iii) pseudo symmetric, (iv) almost pseudo symmetric and (v) weakly pseudo symmetric.
ON THE EXISTENCE OF SOME TYPES OF LP-SASAKIAN MANIFOLDS
Shaikh, Absos A.,Baishya, Kanak K.,Eyasmin, Sabina Korean Mathematical Society 2008 대한수학회논문집 Vol.23 No.1
The object of the present paper is to provide the existence of LP-Sasakian manifolds with $\eta$-recurrent, $\eta$-parallel, $\phi$-recurrent, $\phi$-parallel Ricci tensor with several non-trivial examples. Also generalized Ricci recurrent LP-Sasakian manifolds are studied with the existence of various examples.
