Harmonic and Killing tensor fields in Riemannian spaces with boundary.
Kentaro Yano · Journal of the Mathematical Society of Japan · 1958
In a previous paper [5], we have generalized some of the results on harmonic and Killing vector fields stated in Yano and Bochner [6] to the case of Riemannian spaces with boundary.The purpose of the present paper is to do exactly the same thing for harmonic and Killing tensor fields.The study of harmonic tensor fields in such Riemannian spaces has been already started by Duff and Spencer [3], Conner [2] and Nakae [4].
