  • What is concatenation of regular and non regular?

    If L is a regular language and M is a non-regular language, then the concatenation LM of the two languages is necessarily non-regular.8 déc. 2013

  • Is the concatenation of two non regular languages is non regular?

    Concatenation of two non-regular languages may be regular.
    Constructive Proof: Let L be any non-regular language.
    Now, we know L? is also non-regular.

  • Is the concatenation of two non regular languages is non regular?

    The concatenation of two regular languages, L1 and L2, which are represented using L1. L2 is also regular and which represents the set of strings that are formed by taking any string in L1 concatenating it with any string in L2.
    Example: L1 = { 0,1 } and L2 = { 00, 11} then L1.
