Revisiting Interpolation in Relevant Logics
By: Wesley Fussner, Andrew Tedder
Potential Business Impact:
Finds new ways to make logic puzzles work better.
There are exactly two maximal schematic extensions of the relevant logic R with the variable sharing property. We establish that one of them has a strong form of interpolation for deducibility, thereby giving an example of a well-known relevant logic with interpolation.
