We define atracelike transformationto be a natural family of conjugation invariant mapsfor all dualizable objectsxin any symmetric monoidal-category. This generalizes the trace from linear algebra that assigns a scalarto any endomorphismf:V→Vof a finite-dimensionalk-vector space. Our main theorem computes the moduli space of tracelike transformations using the one-dimensional cobordism hypothesis with singularities. As a consequence, we show that the tracecan be uniquely extended to a tracelike transformation up to a contractible space of choices. This allows us to give several model-independent characterizations of the-categorical trace. By restricting the aforementioned notion of tracelike transformations from endomorphisms to automorphisms one can in particular recover a theorem of Toën and Vezzosi. Other examples of tracelike transformations are for instance given by. Unlike for, the relevant connected component of the moduli space is not contractible, but rather equivalent toorBS1forn= 0. As a result, we obtain a-action onas well as a circle action on.
