Loop-constrained regular polygon maximization conjecture for quantum dot families

Let YY be a finite set of points on a loop Γ\Gamma of fixed length in Rν\mathbb{R}^{\nu}, where ν=2,3\nu=2,3, with the points equidistant in the arc-length variable, and suppose that the balls Bρ(yi)B_{\rho}(y_i) do not overlap. Write HV,YH_{V,Y} for the associated Schrödinger operator and let ϵ1(HV,Y)=infσ(HV,Y)\epsilon_1(H_{V,Y})=\inf\sigma(H_{V,Y}). Loop maximization conjecture. The quantity ϵ1(HV,Y)\epsilon_1(H_{V,Y}) is maximized, uniquely up to Euclidean transformations, when YY is the vertex set of a planar regular polygon with #Y\#Y vertices. This extends the established circular setting to arbitrary loops and asks how geometry affects the ground-state energy in broader quantum dot families.
