A number of important concepts and far-reaching results in this field have come from Alonzo Church (1903–1995), author of a definitive text on logic and noted writer on the history of logic.
The notion of decidability is not one which a beginner in mathematics could explicitly formulate, but both this and related notions, such as that of effective calculability, have a place in the description of the most elementary mathematical concepts. Often our understanding of.....
