Abstract

We discuss the singular Yamabe obstruction B3\mathcal{B}_3 of a hypersurface in a four-dimensional general background. We derive various explicit formula for B3\mathcal{B}_3 from the original definition. We relate these formulas to corresponding formulas in the literature. The proofs are elementary.
