Let .

Now,

The reason why is because is convergent.

The rest of them are similar. - January 28th 2009, 01:20 AMtransgalactic

this expression is not correct

X_n is bounded

the limit of the sequence doesnt equal the limsup

Xn is not convergent

its bounded - January 28th 2009, 10:28 PMIsomorphism

why

X_n is a subsequence which converges

the definition of limsup

is being the sup of the limit group of every subsequence

you cant do limsup X_n

by doing that you split this subsequence into a smaller convergent subsequences

and take the Sup of their limits

which has nothing to do with limsup x_n - January 29th 2009, 09:27 AMThePerfectHacker
