Abstract
We deal with complete linear Weingarten hypersurfaces immersed into locally symmetric Riemannian manifolds whose sectional curvature obeys certain standard constraints. Under an assumption that such a hypersurface satisfies a suitable Okumura type inequality, we apply a version of the Omori–Yau maximum principle to prove that it must be either totally umbilical or isometric to an isoparametric hypersurface having two distinct principal curvatures. When the ambient space is Einstein, we also use a technique recently developed by Alías and Meléndez (Mediterr J Math 17(2): 61, 2020 [6]) to establish a sharp integral inequality for compact linear Weingarten hypersurfaces.
