We study the existence of zero-cycles of degree one on varieties that are defined over a function field of a curve over a complete discretely valued field. We show that local-global principles hold ...

Consider the regression y=f(x̃)+ε , where E(ε|x̃)=0 and the exact functional form of f is unknown, although we do know that f is homogeneous of known degree r. Using a local linear approach, we ...
