Natural operators on tensor fields / E. G. Puninskii. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2014. № 5. P. 58-62 [Moscow Univ. Math. Bulletin. Vol. 69, N 5, 2014.].
In this paper we classify natural operators on tensor fields of different types. We abstain from any assumptions such as symmetry or additional structures and consider arbitrary tensor fields.
Key words: natural operators, tensor fields.
