Categorical Abstract Logic: Hidden Multi-Sorted Logics as Multi-Term Institutions [PDF]
, 2016 Babenyshev and Martins proved that two hidden multi-sorted deductive systems are deductively equivalent if and only if there exists an isomorphism between their corresponding lattices of theories that commutes with substitutions.
