have you discussed lusin"s theorem
Sir at 31.09 , how can you write that , If x does not belongs to UGk , k≥N , then x does not belong to Gk for some k≥N ?
If it's not in union , then it will not be in any set for k≥N
Yes, x is not in every set of the union. Then no need to use the monotonicity of E_n. Thanks for the correction.
Thank you sir for best explanation
Please share my channel with your contacts.
sir what is meant the " nearly" in littlewood principle
Nearly means measure of their difference is less than epsilon.
For example , measurable function f is nearly a continuous function g means m*(f-g)
Vitali covering lemma is the precise statement of measurable set is nearly finite union of disjoint intervals.
