In the present paper, we characterize m-dimensional ζ -conformally flat L P -Kenmotsu manifolds (briefly, (L P K) m ) equipped with the Ricci–Yamabe solitons (RYS) and gradient Ricci–Yamabe solitons (GRYS). It is proven that the scalar curvature r of an (L P K) m admitting an RYS satisfies the Poisson equation Δ r = 4 (m − 1) δ { β (m − 1) + ρ } + 2 (m − 3) r − 4 m (m − 1) (m − 2) , where ρ , δ (≠ 0) ∈ R . In this sequel, the condition for which the scalar curvature of an (L P K) m admitting an RYS holds the Laplace equation is established. We also give an affirmative answer for the existence of a GRYS on an (L P K) m . Finally, a non-trivial example of an L P -Kenmotsu manifold (L P K) of dimension four is constructed to verify some of our results. [ABSTRACT FROM AUTHOR]
