On Representing Sentential Connectives of Lesniewski's Elementary Protothetic
R. Urbaniak · Journal of Logic and Computation · 2006
After a brief presentation of Leśniewski's notation for 1- and 2-place sentential connectives of protothetic, the article discusses a method of extending this method to n ≥ 3-place sentential connectives. Such a method has been hinted at by Luschei, but in fact, no general effective method of defining such functors has been clearly and explicitly given. The purpose of this article is to provide such a method.
