Twisters and signed fundamental domains for number fields

Milton Espinoza, Eduardo Friedman

We give a signed fundamental domain for the action on $R_{+}^{r_{1}} \times C^{*}^{r_{2}}$ of the totally positive units $E_{+}$ of a number field $k$ of degree $n=r_1+2r_2…

A case of the Rodriguez Villegas conjecture

Ted Chinburg, Eduardo Friedman, Fernando Rodriguez-Villegas +1

Let L be a number field and let E be any subgroup of the units O_L^* of L. If rank(E) = 1, Lehmer's conjecture predicts that the height of any non-torsion element of E is bounded b…

The smallest regulator for number fields of degree 7 with five real places

Eduardo Friedman, Gabriel Ramírez-Raposo

In 2016 Astudillo, Diaz y Diaz and Friedman published sharp lower bounds for regulators of number fields of all signatures up to degree seven, except for fields of degree seven hav…

Computing the residue of the Dedekind zeta function

Karim Belabas, Eduardo Friedman

Assuming the Generalized Riemann Hypothesis, Bach has shown that one can calculate the residue of the Dedekind zeta function of a number field K by a clever use of the splitting of…

Signed fundamental domains for totally real number fields

Francisco Diaz y Diaz, Eduardo Friedman

We give a signed fundamental domain for the action on $R_{+}^{n}$ of the totally positive units $E_{+}$ of a totally real number field $k$ of degree $n$ . The domain $\big\{(C_σ,…

The multiplicative anomaly of three or more commuting elliptic operators

Victor Castillo-Garate, Eduardo Friedman, Marius Mantoiu

Zeta-regularized determinants are well-known to fail to be multiplicative. Hence one is lead to study the n-fold multiplicative anomaly M_n(A_1,...,A_n) :=\frac{\det_ζ\Big(\prod_{i…
