 Jul 25 awarded Famous Question Jun 17 comment Constructing any function $\{1 \dots n\} \rightarrow \{1 \dots k\}$ using functions $\{1 \dots n \} \rightarrow \{1,2\}$ Oh, okay - thank you for it then:-) Jun 17 comment Constructing any function $\{1 \dots n\} \rightarrow \{1 \dots k\}$ using functions $\{1 \dots n \} \rightarrow \{1,2\}$ It doesn't really have to be just $[N] \rightarrow [2]$ it can be any construction like: function of pair of functions, but with counterdomain $[2]$ Jun 17 asked Constructing any function $\{1 \dots n\} \rightarrow \{1 \dots k\}$ using functions $\{1 \dots n \} \rightarrow \{1,2\}$ Jun 15 awarded Popular Question Jun 1 awarded Nice Question May 3 awarded Yearling Apr 17 awarded Notable Question Apr 9 comment How to find function $f$ bounded from top by $x^\alpha$ and from bottom by $log^k(x)$ Thanks a lot Clement, this is very clever and nice solution, thanks a lot Apr 9 accepted How to find function $f$ bounded from top by $x^\alpha$ and from bottom by $log^k(x)$ Apr 9 comment How to find function $f$ bounded from top by $x^\alpha$ and from bottom by $log^k(x)$ I edited question with little detail, sorry about it, i assumed it was obvious, cause simplest example $ln^2 x > x^2$ as x goes to 0 shows it couldn't be possible.

Apr 9 comment How to find function $f$ bounded from top by $x^\alpha$ and from bottom by $log^k(x)$ Hey @peter.petrov yes i'm sure Apr 9 asked How to find function $f$ bounded from top by $x^\alpha$ and from bottom by $log^k(x)$ Apr 2 comment Is generating function having use in recurence relations containing division in subscripts? You say $$\sum_{k=2}^r \lambda_k a_0 = a_0$$ That is not true when any $\lambda_k>1$. I understood $\lambda_k$ is constant standing next to $a_{\lfloor \frac{n}{k} \rfloor}$, right?
