Properties of Regular Languages
Every finite language is regular (because we can write a regular expression Proof: Start with a DFA that accepts the regular language "Complete" the DFA |
Another method to demonstrate regularity is to build a finite automaton, such as a deterministic finite automaton (DFA) or a nondeterministic finite automata (NFA).
It gives proof that the language is regular if we can show the automaton can recognize the relevant language.
Are there infinite regular languages?
(.
1) There are a countably infinite number of regular languages.
This true because every description of a regular language is of finite length, so there is a countably infinite number of such descriptions. (.
2) There are an uncountable number of languages.
Thus there are more languages than there are regular languages.
Is every finite set regular?
All finite languages are regular; in particular the empty string language {ε} = Ø* is regular.
Is every language finite?
It is not true that all regular languages are finite.
Even something as simple as 'a*' is a regular expression that matches an infinite set of strings: '' (the empty string), 'a', 'aa', 'aaa', 17 fév. 2015
