Object-space equivalence conjecture for iterated enriched categories

About 1 year old · traced to

Let C\mathcal{C} be an (∞,n)(\infty,n)-category, and let On−1\mathrm{O}_{n-1} and Θn\Theta_n be the indexing shapes used to define the iterated constructions T˙n(C)\dot{\mathcal{T}}^n(\mathcal{C}) and L˙n(C)\dot{\mathcal{L}}^n(\mathcal{C}). Object-space equivalence conjecture. The natural maps

Fun(On−1,C)≃⟶T˙n(C)≃\mathrm{Fun}(\mathrm{O}_{n-1},\mathcal{C})^\simeq\longrightarrow\dot{\mathcal{T}}^n(\mathcal{C})^\simeq

and

Fun(Θn,C)≃⟶L˙n(C)≃\mathrm{Fun}(\Theta_n,\mathcal{C})^\simeq\longrightarrow\dot{\mathcal{L}}^n(\mathcal{C})^\simeq

are equivalences of spaces. The preceding lemma proves surjectivity on π0\pi_0 for the first map; the conjecture asserts the stronger equivalence statement for both maps.
