Pfaffians, the G-Signature Theorem and Galois de Rham discriminants
T. Chinburg, G. Pappas, M. J. Taylor
We study equivariant de Rham discriminants associated to arithmetic varieties which support a tame action by a finite group; we form these discriminants by endowing the de Rham coh…

Epsilon constants and equivariant Arakelov Euler characteristics
T. Chinburg, G. Pappas, M. J. Taylor
We study equivariant Arakelov-Euler characteristics of hermitian sheaves on arithmetic varieties which support a tame action by a finite group G. The tameness of the group action a…

Epsilon constants and Arakelov Euler characteristics
T. Chinburg, G. Pappas, M. J. Taylor
We conjecture that the logarithm of the absolute value of the constant in the functional equation of the Hasse-Weil L-function of a variety X over Z is equal to a certain Arakelov…
