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…

Self-intersections of the Riemann zeta function on the critical line
William Banks, Victor Castillo-Garate, Luigi Fontana +1
We show that the Riemann zeta function ζ has only countably many self-intersections on the critical line, i.e., for all but countably many z in C the equation ζ(1/2+it)=z has at mo…
