Abstract
Certain distributivity results for Łukasiewicz's infinite-valued logic Łℵ0 are proved axiomatically (for the first time) with the help of the automated reasoning program OTTER. In addition, non distributivity results are established for a wide variety of positive substructural logics by the use of logical matrices discovered with the automated model-finding programs MACE and MAGIC.
