Cardinality of a subset of smooth numbers
Recall: An $n$-smooth number is an integer whose prime factors are all less than or equal to $n$.
Let $k$ and $N$ two integers with $0\leq k\leq N$. Let's put $H= \{n\in[0,N]\ s.t.\ n\ is\ k-smooth\} …

Rough numbers in short interval
A positive integer $n$ is called $k$-rough if all of the prime factors of $n$ strictly exceed $k$.
For $k$ fixed and $n$ large, what's the shortest interval $[n,n+t]$ that contains a $k$-rough number …
