Gauge Dependence of Effective Action and Renormalization Group Functions in Effective Gauge Theories
, 2000

The CaswellWilczek analysis on the gauge dependence of the effective action and the renormalization group functions in YangMills theories is generalized to generic, possibly power counting non renormalizable gauge theories.

The CaswellWilczek analysis on the gauge dependence of the effective action and the renormalization group functions in YangMills theories is generalized to generic, possibly power counting non renormalizable gauge theories. It is shown that the physical coupling constants of the classical theory can be redefined by gauge parameter dependent contributions of higher orders in "hbar" in such a way that the effective action depends trivially on the gauge parameters, while suitably defined physical beta functions do not dependent on those parameters.
Schemes over F1 and Zeta Functions
, 2009
"... We determine the real counting function N(q) (q ∈ [1, ∞)) for the hypothetical “curve” C = Spec Z over F1, whose corresponding zeta function is the complete Riemann zeta function. Then, we develop a theory of functorial F1schemes which reconciles the previous attempts by C. Soulé and A. Deitmar. ..."

We determine the real counting function N(q) (q ∈ [1, ∞)) for the hypothetical “curve” C = Spec Z over F1, whose corresponding zeta function is the complete Riemann zeta function. Then, we develop a theory of functorial F1schemes which reconciles the previous attempts by C. Soulé and A. Deitmar. Our construction fits with the geometry of monoids of K. Kato, is no longer limited to toric varieties and it covers the case of schemes associated to Chevalley groups. Finally we show, using the monoid of adèle classes over an arbitrary global field, how to apply our functorial theory of Moschemes to interpret conceptually the spectral realization of zeros of Lfunctions.
