Query: An approach to F_1 via the theory of lambda rings   We model the field $F_1$ of one element as a lambda ring $\bf Z$ with the
canonical lambda structure. We show that then we can calculate the Riemann zeta
function of integers in two ways: the first, geometrical, as a zeta function of
the affine line over $F_1$ and the second, categorical, as a zeta function of
the category of modules over $F_1$.
