In this paper we investigate the geometry of doubly twisted product manifolds and we study the harmonicity and biharmonicity of maps between doubly twisted product Riemannian manifold. Also we characterize the conformal biharmonic maps and construct some new proper biharmonic maps.
Keywords: harmonic maps, biharmonic maps, conformal maps, proper biharmonic maps, doubly twisted product manifolds
