comment Why Refine does not simplify Cos[2*Pi*FractionalPart[1/2*(i + j + k)]] to $(-1)^{i+j+k}$?
@Mr.Wizard I'm sorry that I have no spare time to participate on this site now. I hope I'll be back in September or earlier. I was glad to talk with Leonid at the recent Wolfram conference in St. Petersburg.

@Artes I think that it is not a duplicate since Refine/FullSimplify works bad with FractionalPart.
