Soliton types on Lorentzian para-Sasakian manifolds

This thesis consists of three charpters. In the first charpter, the basic concepts related to the subject are given. In the second charpter, basic definitions and theorems about almost contact metric manifolds, contact metric manifolds and paracontact metric manifolds are given. In the third and fourth parts, Lorentzian para-Sasakian manifolds were defined and various curvature conditions were studied by studying Ricci Soliton and 𝜂-Ricci soliton types on this manifold.
