Abstract
We analyze the structure of ideals generated by some classes of 2 × 2 permanents of hypermatrices, generalizing [Citation9] on 2 × 2 permanental ideals of generic matrices. We compare the obtained structure to that of the corresponding determinantal ideals in [Citation11]: as expected, the permanental ideals have many more (minimal) components. In the last two sections, we examine a few related classes of permanental ideals.
