### Abstract

mathematical quantum theory. This trend was observed in [3], mainly in relation to Hopf algebroids, and continued in [8] with a general account of Frobenius monoids. Below we list some of the ∗-autonomous partially ordered sets A = (A, p, j, S)

Without going into much detail, we also note some features of the convolution [A , V ] (defined in =-=[1]-=-) of a given such A with a complete ∗-autonomous monoidal category V . A monoidal functor category of this type is a completion of A , with an appropriate universal property; it is always again ∗-auto... |
