Constant-curvature packing conjecture. If

Hamilton's conjecture. The metric $g(t)$ converges to a metric of constant scalar curvature as $t\to\infty$.

Let $(M^3,J,\mathring{\theta})$ be a closed spherical CR $3$-manifold with positive Tanaka-Webster scalar curvature and vanishing torsion. Consider the normalized CR Yamabe flow st…
