Property 4. The difference of two regular set is regular. Proof − Let us take two regular expressions − RE1 = a (a*) and RE2 = (aa)* So, L1 = {a, aa, aaa, aaaa, ....} (Strings of all possible lengths excluding Null) L2 = { ε, aa, aaaa, aaaaaa,.......} (Strings of even length including Null) L1 - L2 = {a, aaa, aaaaa, aaaaaaa, ....} (Strings of all odd lengths excluding Null) RE (L1 - L2 ) = a (aa)* which is a regular expression. Hence, proved Pls explain this sir
Are you clear all concepts but not difine how to proof this theorem , I don't know ho to proof difference theorem if any body knows pls described for me . Lots of thanks 😊👍
Sir in 3rd property i.e closure of a language is regular. U took L= {a} then then L*= a*= €,a,aa,aaa..... Now after apply * operation on L......L* all values not belongs to L so how it's closure? Pls explain how it works here🙏
Sir, when we say Regular languages are closed under union then it implies that union of 2 or more Regular languages is always regular. but union of infinite regular languages might not be regular. #Conceptual_doubt if L1 =lamda, L2={ab} L3={aabb} L4={aaabbb} L5={aaaabbbb} and so on.. then L1 U L2 U L3 U ........ will give l={a^n b^n ; n>=0} which is basically non regular language. then how can we say that union is closed under union?? kindly help!

[00:00] Regular language properties are important in TOC and competitive exams
- Regular languages have properties like union, concatenation, complementation, intersection, difference, reversal, homomorphism, and quotient
- Teasers and closed captioning are examples of regular language properties
- Regular languages can be finite or infinite and are used in computer science and linguistics
[03:07] Regular languages have a closure property and can be represented by finite automata.
- Regular languages have a closed operation that accepts the last word
- Regular languages are closed under finite union and concatenation
- Finite automata can be used to represent regular languages
[06:15] Regular languages and finite automata design concepts are discussed in detail
- Regular languages can be represented by finite automata
- Designing a DFA involves selecting a start state and final state
- Complementation of regular languages involves inverting the final and non-final states
- The intersection and union of regular languages are also closed under regular languages
Thanks sir, No one can explain like you.

Thanku so much sir ji

Complementation is defined by difference
Intersection is defined by complementation
Difference is defined by intersection.
Then it is a loop right?
Thank you sir ❤️
Thank you so much sir
Thank you sir
Sir subset ka liya bhi not closed hai.
Property 4. The difference of two regular set is regular.
Proof −
Let us take two regular expressions −
RE1
= a (a*) and RE2
= (aa)*
So, L1
= {a, aa, aaa, aaaa, ....} (Strings of all possible lengths excluding Null)
L2
= { ε, aa, aaaa, aaaaaa,.......} (Strings of even length including Null)
L1
- L2
= {a, aaa, aaaaa, aaaaaaa, ....}
(Strings of all odd lengths excluding Null)
RE (L1
- L2
) = a (aa)* which is a regular expression.
Hence, proved
Pls explain this sir
on subtracting L1 and L2, we get -ε, but you did not write it?
Students ke lia farishtey hoo app😊
Thankyou sir

Given two regular languages L1, L2, prove by construction that : i) L1^R n L2^R is regular, ii) L1* U L2 ^R is regular.
Plice sir solution send me
thank you sir
Sir in 3rd property i.e closure of a language is regular.
U took L= {a} then then L*= a*= €,a,aa,aaa.....
Now after apply * operation on L......L* all values not belongs to L so how it's closure?
Pls explain how it works here🙏
Sir,
when we say Regular languages are closed under union then it implies that union of 2 or more Regular languages is always regular.
but union of infinite regular languages might not be regular.
#Conceptual_doubt
if L1 =lamda,
L2={ab}
L3={aabb}
L4={aaabbb}
L5={aaaabbbb}
and so on..
then L1 U L2 U L3 U ........ will give l={a^n b^n ; n>=0}
which is basically non regular language. then how can we say that union is closed under union??
kindly help!
If L1=a^n and L2= a^n. Then whether a^n.b^n is regular?
Yes but a^n is not regular
@@AbhishekTiwari-xt1kt It is regular.
