Self-repulsiveness thresholds for regularized alpha-energy

Let EαE_\alpha be the regularized α\alpha-energy of a smooth closed surface. Self-repulsiveness with respect to C0C^0-topology means that sequences of embedded surfaces converging in C0C^0 to a singular surface with a double point cannot keep their energies bounded while distinct points approach one another in ambient distance. Also consider surfaces in R3\mathbb{R}^3 whose curvature is bounded by a constant b>0b>0.

Self-repulsiveness conjecture. The regularized α\alpha-energy EαE_\alpha for smooth closed surfaces is self-repulsive with respect to C0C^0-topology if and only if α4\alpha\leq -4, whereas EαE_\alpha restricted to the space of surfaces in R3\mathbb{R}^3 with curvature bounded by bb is self-repulsive if and only if α3\alpha\leq -3.

The local estimates preceding the conjecture show that orthogonal double points and cone singularities produce divergent energy for α4\alpha\leq -4, while tangential double points have the threshold α3\alpha\leq -3. The conjecture asserts that these thresholds characterize self-repulsiveness in the stated spaces; the supplied text gives no resolution.
