Let $X$ be a compact, acyclic, orientable circle bundle of dimension $n$, and let $k[pi_1(X)]$ denote its fundamental group algebra over a field $k$. A superpotential algebra is an…

Monotone invariant conjecture. In every dimension $n$, there is such a homotopy $n$-manifold numerical invariant $I_n$ that is positive and finite on every circle bundle over a clo…
