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:

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 $x\mapsto e^{inx}$, $n\in\mathbb Z$. 7h reviewed No Action Needed How can I calculate $\int \frac{\sec x\tan x}{3x+5}\,\mathrm dx$ 7h reviewed Reject suggested edit on Estimate $\frac{(\frac{1}{2}\lambda_{\text{min}}(A+A^T))^2}{\lambda_{\text{max}}A^TA}<1$ 7h reviewed Approve suggested edit on DFA : if W ϵ {a,b,c}* (|w|a-|w|b+c) mod 3>=1 7h reviewed Looks Good Shown that this matrix is a representative of a group. 7h reviewed No Action Needed Finding distance of point from 4D ray 7h reviewed Approve suggested edit on Prove that $\sin(\frac{\pi}{3}+x)=\cos(\frac{\pi}{6}-x)$ 7h reviewed Reject suggested edit on Showing iterates of a complex function on the upper half plane converges uniformly on compact sets 7h reviewed Close If the sequence converges, find it's limit. 7h reviewed Leave Open What is the definition of sigma field generated by random variable $X$? 7h reviewed No Action Needed Variation of Nim: Player who takes last match loses 7h reviewed No Action Needed Find the rank of the given matrix 8h revised Find spikes in dataedited tags 8h answered $L^p$-limit and pointwise limit 8h reviewed Approve suggested edit on Normal distribution exercise 8h revised A Criterion for being Sylow p-groupadded 6 characters in body 8h reviewed No Action Needed Laplace Transform of tsin(at) using only the definition 8h reviewed Looks Good Proving that a function is onto in an interval
