WebTheorem. ETM = {hMi M is a TM and L(M) = ∅} is undecidable. Proof. We show ATM is reducible to ETM. First, given hM,wi, a Turing machine can modify the encoding of M, to transform M into M′, which recognises L(M)∩{w}. This is what the new machine M′ does on input x: 1. If x 6= w, reject. 2. If x = w, run M on w and accept if M accepts. WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
