Coinduction preservation conjecture for compatible indexing categories

About 5 years old · traced to

Let (Oa,Om)(\mathcal O_a,\mathcal O_m) be a compatible pair, and let H/KH/K be admissible for Om\mathcal O_m. Write Map⁡K(H,−)\operatorname{Map}^K(H,-) for coinduction from KK to HH.

Coinduction preservation conjecture. Coinduction restricts to a functor

Map⁡K(H,−) ⁣:iK∗Oa→iH∗Oa.\operatorname{Map}^K(H,-)\colon i_K^*\mathcal O_a\to i_H^*\mathcal O_a.

In this case, coinduction is said to preserve Oa\mathcal O_a.

This conjecture asserts closure of the relevant indexing-category maps under coinduction and is the condition needed for constructing norm functors by left Kan extension. The source gives no resolution of the conjecture.
