In December 1920, M. Schönfinkel presented in a report to the Mathematical Society in Göttingen a new type of formal logic based on the concept of a generalized
function whose argument is also a function (Schönfinkel 1924). This mathematical
discipline was subsequently termed combinatory logic
by Curry and "
-conversion"
or "
-calculus"
by Church. Combinators can be used in the study of algebra, topology, and category
theory, and have found application in the study of programs in algorithmic languages.
