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:

comment Absolute continuity reflected in Fourier coefficients?
There exists some $f\in\mathbb L^1(\nu)$ such that $\mu(A)=\int_Af(x)d\nu(x)$ for each $A$. The function $f$ can be approximated in $\mathbb L^1(\nu)$ by a continuous function in the unit interval. Hence for a fixed $\varepsilon$, there is $f_\varepsilon$ continuous such that $\lVert f-f_\varepsilon\rVert_{\mathbb L^1(\nu)}\lt\varepsilon$. Then we approximate uniformly on the unit interval the function $f_\varepsilon$ by lnear combinations of functions of the form $x\mapsto e^{inx}$, $n\in\mathbb Z$.
