Preservation of admissibility of inference rules in the logics similar to $S4.2$
V. V. Rybakov, V. V. Rimatskii Krasnoyarsk State University
Abstract:
We show that an arbitrary finitely approximable logic extending $S4.2(Grz.2, KC)$ preserves all admissible inference rules of the logic $S4.2(Grz.2, KC)$ if and only if this logic possesses the so-called semantic cocovering property.
