Closure under Regular Operations •We started this before and did it for Union only –Union much simpler using NFA •Concatenation and Star much easier using NFA •Since DFAs equivalent to NFAs we can now just use NFAs •Fewer states to keep track of because we can act as if we always “guess”correctly 9/18/20 Theory of Computation

What is an operation on a language?
- Operations on Languages Recall: A language is a set of strings We can consider new languages derived from operations on given languages { e.g., L 1[L 2, L 1L 2, ... A simple but powerful collection of operations: { Union, Concatenation and Kleene Closure Union is a familiar operation on sets. We defne and explain the other two operations below.
