On properties of the minus partial order in regular modules

2020    Ungor, Burcu; Halicioglu, Sait; Harmanci, Abdullah; Marovt, Janko

We investigate properties of the minus partial order in regular modules, present new characterizations of this order, and generalize some known results. We introduce a new relation in the general module theoretic setting that is analogous to the space pre-order on complex matrices and study how it is related to the minus partial order.
