I'm a Ph.D. student, working on limit theorems of probability theory.

  1. When I edit a post, I suggest the owner to check whether I didn't change the meaning.

  2. The less detailed is the OP (attempts, etc...), the less my answer will be.

My activity on math.stackexchange consists in:

Yes it's true. It has been discussed in this site, maybe you will be faster than me to find a link.

comment How to prove that an operator is compact?
What I meant is that given a subsequence of $(\lambda_j)$, you can extract from this subsequence a further subsequence which converges to $0$. This is equivalent to the fact that the whole sequence converges to $0$, is it?

comment Show that if $|f(z)| \leq M |z|^n$ then $f$ is a polynomial max degree n
The degree cannot be larger than $n$ because $|f(z)|\leqslant |z|^n$ (consider this inequality for $z$ with large modulus).
