I am studying research paper " A note on odd zeta values " by Tanguy Rivoal and Wadim Zudilin" . >Note-> This question has been closed 2 times on math stackexchange. Earlier it was posted on MathOverflow but people here said it should be posted on math stackexchange. But now they have closed it 2 times . >Please help I am badly struck on it. I don't see a way. Edit 1- Notations [![enter image description here][1]][1] >I couldn't think about how authors write the equation - we obtain $\phi_{(n) }^{-1} ( F(t) (t+m)^5 )_{ t=-m} $ $ \epsilon $(belongs to) integers for m= 0 ,1,...,n by defininig $\phi_{(n)} = \prod_{2√n<p\leq n } p^{\rho_0(n/p) } $ .Please see last 2 lines of image posted below , I have highlighted the part in which i have doubt .[![enter image description here][2]][2] [![enter image description here][3]][3] I have understood everything in research paper till this argument and I don't know how authors derives this. >I think they are using [12, lemma1] (Paper-" One of odd zeta values from $\zeta(5)$ to $\zeta(25) $ is irrational by elementary means " By Wadim Zudilin )whose image I am posting below but I am not able to obtain this relation from the lemma. Image of lemma -> [![enter image description here][4]][4] Can someone please help how to deduce this equation $\phi_{(n) }^{-1} ( F(t) (t+m)^5 )_{ t=-m} $ $\epsilon$(belongs to) integers.
