Abstract:
The interpolation problem over Johansson's minimal logic $\mathrm{ J}$
is considered. We introduce a series of Johansson algebras, which
will be used to prove a number of necessary conditions for a
$\mathrm{ J}$-logic to possess Craig's interpolation property $\mathrm{
(CIP)}$. As a consequence, we deduce that there exist only finitely
many finite-layered pre-Heyting algebras with $\mathrm{ CIP}$.
Keywords:
finite-layered pre-Heyting logic, Craig's interpolation property,
Johansson algebra.
