Abstract: The parallel product operator may be defined very easily on flow event structures. The authors show that for such structures satisfying a particular constraint, which is preserved by usual process operators, this product may be characterized as a categorical product.
Keywords: parallel product; flow event structure; categorical product; process operator.
