Louboutin, Stéphane R. Real zeros of Dedekind zeta functions. (English) Zbl 1322.11118 Int. J. Number Theory 11, No. 3, 843-848 (2015). The author applies some ideas of H. Kadiri [Int. J. Number Theory 8, No. 1, 125–147 (2012; Zbl 1279.11110)] and S. B. Stechkin [Math. Notes 8, 706–711 (1971); translation from Mat. Zametki 8, 419–429 (1970; Zbl 0233.10020)] to enlarge the value of \(c\) for which the interval \((1-c/\log d(K),1)\) contains at most \(m\) roots of the Dedekind zeta-function \(\zeta_K(s)\).In [Manuscr. Math. 125, No. 1, 43–67 (2008; Zbl 1137.11072), Corollary 9], the author showed for non-normal sextic \(CM\)-fields \(K\), not containing any imaginary quadratic subfield, and whose totally real cubic subfield \(F\) is non-normal, that if \(h^-(K)=1\) and \(2\) splits in \(F\), then \(d(K)\leq 50\cdot10^{24}\). The new value of \(c\) permits to diminish this bound to \(d(K)\leq 4\cdot10^{24}\).
