[PDF] 1 Closure Properties
Regular Languages are closed under intersection, i e , if L1 and L2 are regular then L1 ∩ L2 is also regular Cross-Product Construction Let M1 = (Q1,Σ,δ1,q1,F1) and M2 = (Q2,Σ,δ2,q2,F2) be DFAs recognizing L1 and L2, respec- tively

Intuitively, a string is in L1 ∪ L2 ∪ Lk iff it is in An operator is idempotent if the result of applying it to two of the same values as arguments with the same set of variables, is: 1 If L is a regular language over alphabet Σ then L = Σ∗ \ L is also regular Proof: Let L closed under complement and intersection Automata

(15 points) Prove or disprove the following statement: If M = (Q,Σ, δ, q0,F) is a minimal DFA for a regular language L, then M = (Q,Σ, δ, q0,Q − F) is a minimal DFA for L (10 points) The symmetric difference of 2 sets S1 and S2 is defined as (a) Construct regular set L1 − L2 = L1 ∩ L2 = L This can be done since there

(a) Union of two non-regular languages cannot be regular Ans: False Let L1 Since, L1 is regular, hence its intersection with L i e L1 ∩ L = L2 is regular (since regular (c) The set of finite length strings over a countably infinite alphabet is countably infinite Ans: True To detect this, the machine cannot have less than

A language is called regular if it is accepted by a finite state automaton Let A and B be languages (remember they are sets) We define the following operations
[PDF] Regular Expressions
Regular expressions can be seen as a system of notations for denoting ϵ-NFA They form an there is no intersection operation 1 union L1 ∪ L2 of two languages L1 and L2 2 concatenation L1L2 this is the set of all words x1x2 with xi ∈ Li If L1 or L2 ϵ /∈ L(R) then this is the only solution of the equation x = Rx + S
