• When formulating universal properties for objects in a dagger category, one usually expects a universal property to characterize the universal object up to unique unitary isomorphism. We observe that this is automatically the case in the important special case of $$\hbox {C}^*$$-categories, provided that one uses enrichment in Banach spaces. We then formulate such a universal property for infinite direct sums in $$\hbox {C}^*$$-categories, and prove the equivalence with the existing definition… CONTINUE READING
