Good factors of L-function
Great! Here's a precise reference: Serre's Abelian L-adic representations book defines the L-function via arithmetic frobenius (p.I-16) and specifies the euler factor as the characteristic polynomial evaluated at the appropriate number. Thanks! |

Good factors of L-function
This is pretty wierd. (1) Of course, fixed pts of arithmetic or geometric frobenius of vars/finite fields obviously agree, only their characteristic polynomials disagree. (2) The eigenvalues of geometric frobenius are algebraic integers, (hence not arithmetic frobenius). (3) Charpolys appearing in Weil conjectures (hence local zeta funcs) are of geometric frob. and I thought that the Hasse-Weil zeta function of vars/num fields are products of the local zeta functions (evaluated at various pts). If this last result is true, do we have a contradiction? |

Learning a little Motivic Cohomology
Hi Andrew, thanks for your comments and the reference - I wasn't aware of it. I agree, Motivic cohomology has the ability to describe special values of $L$-functions of smooth projective varieties (and more generally) as predicted by Beilinson. |
