Alonzo Church (June 14, 1903 – August 11, 1995) was an American mathematician, computer scientist, logician, and philosopher who made major contributions to mathematical logic and the foundations of theoretical computer science. He is best known for the lambda calculus, the Church–Turing thesis, proving the unsolvability of the Entscheidungsproblem ("decision problem"), the Frege–Church ontology, and the Church–Rosser theorem.Alongside his doctoral student Alan Turing, Church is ...
Oct 21, 2021 · Alonzo Church (1903–1995) was a renowned mathematical logician, philosophical logician, philosopher, teacher and editor. He was one of the founders of the discipline of mathematical logic as it developed after Cantor, Frege and Russell.
Like his more famous pupil Alan Turing (1912-1954), Alonzo Church contributed significantly to the foundations of computer science. He is credited, along with Turing, with formulating a key principle concerning computer logic involving recursion, or the recurring repetition of a given operation.
Church introduces a connective for propositional identity for which we will use a bold equality sign, so that (in addition to identities between propositional variables such as “\(p = q\)”) identities between wffs are well formed.
