% Bibliography for "An infinite family of irrational dilogarithm values at real quadratic units" (Theorem V, with % Theorem U = pi^2 - 18 log^2 phi as corollary). Compiled 2026-11-07; HakimogluBrown2026 added for the V revision. % Entries Hata1990 ... ViolaZudilin2018, SaffTotik, Lewin1981, Mathlib, Mathlib4, LeanFour, PNTplus, zeta5 are copied % verbatim from lean_chi2/paper/references.bib, where each carries a verification comment (checked 2026-10-16/18). % Own work: "Krisman, S." (rendered "S.

Hexagon 2611.00170 (Waldschmidt subgroup theorem in % Lean) and 2611.00171 (four exponentials at CM and Beta periods) are not cited: this paper does not refer to that work. % The chi_2(1/3) paper is in the public repository telaviv/chi2-irrationality as paper/chi2-irrationality.pdf % (added in commit 55fa479, 2026-10-18). That paper cites its own repository as the entry Chi2Repo below (with % commit 0d781d2). We cite commit 35b030d (2026-10-22), from which the ported files were taken; it was origin/main % on 2026-11-07. Reference check 2026-11-09: the public main of telaviv/chi2-irrationality is now 184b987 % (2026-11-10 UTC, GitHub API); 35b030d is still in its history.
