Hi,
I´m looking for Chebyshev´s theorem which speaks ofsays that the following inequality $|x(k)-y|<3/k$ has infinitely many solutions, where $x(k)=x_0+k\alpha (mod 1)$$x(k)=x_0+k\alpha \pmod 1$, $\alpha$ is an irrational number, and $x_0,y\in S^{1}$$x_0,y\in S^1$. AnyoneDoes anybody know, what the correctexact formulation of this theorem?
