(4 points) Suppose a language L1 is defined recursively as follows, over E = {0,1}: EL1 = {0x1 | x ∈ L1}; nothing else is in L1. Give a non-recursive description of L2 where L2 = L1 - L∞. Prove that L∞ = L2.

Step 1
It states that L1 is the set of all strings that can be obtained by concatenating "0" with a string x, where x belongs to L1. In other words, L1 consists of all strings that start with "0" followed by a string from L1. Now, let's define L∞. L∞ is the set of all Show more…

Let language L1 be a subset of the language {w1cw2 | w1, w2 ∈ Σ* and c ∉ Σ*}. Let language L2 = {w1 ∈ Σ* | for some w2 ∈ Σ*, w1cw2 ∈ L1}. If L1 is Turing recognizable, is L2 Turing recognizable? If L1 is Turing decidable, is L2 Turing decidable? Explain your answer.

Consider the sequence {bn}n=1 defined recursively by b1 = 3 and, for any integer n >= 2, bn = -nbn-1. Find b2, b3, b4, and b5.

Let <M1>, <M2>, <M3>, ... be an enumeration of all Turing machines with input alphabet {0, 1}. Let w1, w2, w3, ... be an enumeration of all binary strings. Prove that D = {wi | i ≥ 0 and Mi does not accept wi} is not Turing-recognizable. Hint: Use contradiction—assume D is Turing-recognizable and then use diagonalization.
