The equivalence conjecture for oriented dagger and disk-like higher categories

From papers

Let SOnSO_n-dagger categories be the higher categories equipped with the oriented tangential structure described in the source, and let disk-like nn-categories be the structures introduced by Morrison and Walker in blob-homology. The equivalence conjecture for oriented dagger and disk-like higher categories. There is an equivalence between SOnSO_n-dagger categories and disk-like nn-categories. This is motivated by the established equivalence between disk-like 2-categories and pivotal bicategories, together with the corresponding two-dimensional description of SO2SO_2-dagger categories; the higher-dimensional equivalence remains open.
