Likely violation of SPIP: Everything Retkes

Everything involving Retkes' name here looks like pollution to me (source: PhD in pure maths). I smell self-promotion: Someone with the time and expertise should clean up, and possibly mark several of these pages for deletion according to WP:SPIP — Preceding unsigned comment added by 172.254.63.183 (talk) 06:08, 4 May 2013‎

Dear X. I would like to turn your attention to this article:

Some applications of Retkes' identity P Kórus - Archiv der Mathematik, 2015 - Springer

Abstract. We present some formulas for certain numeric sums related to the Riemann zeta function. The main tool used in our investigation is Retkes’ identity. We get a formula for ζ(3) with the Euler beta function in it. Mathematics Subject Classiﬁcation. Primary 11Y60; Secondary 11M06, 33B15. Keywords. Retkes’ identity, Zeta(3), Binomial coeﬃcients, Alternating sums. White Tiger (talk) 11:49, 29 July 2018 (UTC)[reply]

Section "A corollary on Vandermonde-type integrals"

I've removed much of the low-density crud from this section. According to User:Tudor987, whe whole section was created by User Vezér who self-promoted in many ways his non-notable results in Wikipedia. This section is likely from his work, which I can't access—it's behind a paywall, and I won't be on my University's campus to access the physical copy for another month. Without a simple (i.e. 1-paragraph) proof, it's probably not on-topic for the article. Bernanke's Crossbow (talk) 02:26, 26 June 2019 (UTC)[reply]
