Schur [3] proved that the maximum number of mutually commuting linearly independent complex matrices of order n is ln2 /4J + 1. Forty years later, Jacobson [2] gave a simpler derivation of Schur's Theorem and extended it from algebraically closed fields to arbitrary fields.

WebFeb 19, 2013 · 13. To understand how to represent Booleans in lambda calculus, it helps to think about an IF expression, "if a then b else c". This is an expression which chooses the first branch, b, if it is true, and the second, c, if it is false. Lambda expressions can do that very easily: lambda (x).lambda (y).x. will give you the first of its arguments, and.

This was done by Alonzo Church in 1935 with the concept of "effective calculability" based on his λ-calculus, and by Alan Turing the next year with his concept of Turing machines. Turing immediately recognized that these are equivalent models of computation. The negative answer to the Entscheidungsproblem was then given by Alonzo Church in 1935–3…
