Abstract: In this paper, we introduce the D-star order, T-star order, and P-star order on the class of dual matrices. By applying the matrix decomposition and dual generalized inverses, we discuss properties, characterizations, and relations among these orders, and illustrate their relations with examples.

Key words: Dual generalized inverse, D-star partial order, P-star partial order, MoorePenrose dual generalized inverse, Dual Moore-Penrose generalized inverse
