Connectedness of the approximate-root set
Let be a regular ring, let , and assume that either is complete or . Let be the approximate roots common to and , and write the relevant standard expansions using monomials and . Approximate-root connectedness conjecture. The set defined by the valuation inequalities and sign conditions in the source is connected; likewise, the set defined by the displayed domination inequalities and the two sign conditions is connected. These are explicit proposed reductions of the Connectedness conjecture; the paper does not establish these assertions in general.
