Reverse-order law for weighted Moore--Penrose inverse of tensors
arXiv:1901.01527 · doi:10.1007/s43036-019-00005-0
Abstract
In this paper, we provide a few properties of the weighted Moore--Penrose inverse for an arbitrary order tensor via the Einstein product. We again obtain some new sufficient conditions for the reverse-order law of the weighted Moore--Penrose inverse for even-order square tensors. We then present several characterizations of the reverse-order law for tensors of arbitrary order.
