turing recognizable languages closed under concatenation


Are Turing decidable languages closed under intersection?

Theorem: Turing decidable languages are closed under intersection. Proof: 1 be a TM which decides L1, and 1 Theorem: Turing decidable languages are closed under intersection. Proof: Let M 1 be a TM which decides L 1 , and let M 2 be a TM which decides L 2 Let C be a TM which makes a copy of the input: (s, # w #) ?* (h, # w # w [#]).

How to recognize two Turing-recognizable languages?

For any two Turing-Recognizable languages L 1 and L 2, let M 1 and M 2 be the TM s that recognize them. We construct a TM M ? that recognize the union of L 1 and L 2: Run M 1 and M 2 alternately on w step by step. If either accpts, a c c e p t. If both half and reject, r e j e c t.

What are the closing properties of decidable languages?

Closure Properties of Decidable Languages Decidable languages are closed under ?, °, *, ?, and complement Example: Closure under ? Need to show that union of 2 decidable L’s is also decidable Let M1 be a decider for L1 and M2 a decider for L2 A decider M for L1 ?L2: On input w: 1. Simulate M1 on w. If M1 accepts, then ACCEPT w.

Are regular languages closed under concatenation?

Regular Languages Closed under Concatenation Theorem 1.26: The class of Regular Languages is closed under the concatenation operation Theorem 1.26 (restated): If Aand Bare regular languages, then so is A? B Proof Idea: Use FSMs for Aand Bto create a machine that recognizes the union
