Abstract. In this paper, we introduce the doubly nonnegative (dnn) tensor, completely positive (cp) tensor, binary cp tensor and cp pseudograph. Some necessary and sufficient conditions for a tensor to be binary cp are also offered. We also present some conditions for a dnn tensor to be cp by its associated pseudograph.
