Theorem: Every finite language is regular Proof: If L is the empty set, then it is defined by the regular expression ∅ and so is regular If it is

True; all finite languages are regular languages and regular languages are closed False; we can show this language in not regular using techniques similar to
hand
Every finite language is regular (because we can write a regular expression for it) B The union of two regular languages is regular (if E is a regular expression for one language and F for another, then E+F is a regular expression for the union of the two languages
Regular Language Properties
8 fév 2013 · This fifth problem set explores the regular languages, their properties, and their limits This will Prove that any finite language is regular
Problem Set
Every RL defined on alphabet Σ is accepted by at least 1 of these DFAs, Statement: Every finite language is regular – Proof: 1 If finite language L is empty, it is
automata rls
Design a finite automaton which accepts a given language Prove closure properties of the class of regular languages Is every finite language regular?

For the true ones (if any) give a proof outline (a) Union of two non-regular languages cannot be regular (g) Every finite subset of Σ∗ is a regular set
