The study of Ricci solitons on α-cosymplectic manifolds

This master's thesis is a five-part study. The first chapter of the thesis is devoted to basic literature information and the context of the thesis. The second chapter of the thesis contains the most necessary basic definitions and concepts. The third chapter of the thesis presents α-cosymplectic manifolds and their fundamental curvature properties. After discussing the basic concepts related to Ricci solitons in the fourth chapter of the thesis, some results obtained in the last chapter will be used to calculate α-cosymplectic manifolds admitting Ricci solitons. In the last chapter of the thesis, some results concerned with Ricci solitons (g,ξ,λ) on α-cosymplectic manifolds have been obtained by using different semi-symmetric structures.
