Definition has_binprod_ump_weq_universal (HB_2_1 : is_univalent_2_1 B) (p : bincoprod_cocone) : has_bincoprod_ump p ≃ is_universal_coprod_cocone p. Proof. use weqimplimpl. - exact (make_is_universal_coprod_cocone HB_2_1 p). - exact (universal_coprod_cocone_has_ump p). - apply isaprop_has_bincoprod_ump. exact HB_2_1. - apply isaprop_is_universal_inserter_cone. exact HB_2_1. Defined.
