Universality of the oriented minimum spanning tree limit for positive continuous weights

Less than 1 year old · traced to

Let (We⃗)e⃗∈E⃗(W_{\vec e})_{\vec e\in\vec E} be i.i.d. weights with continuous distributions supported in (0,∞)(0,\infty), rather than i.i.d. Exponential(1)(1) weights. Let the main theorem assert the stated local-limit relationship between the oriented minimum spanning tree and the uniform spanning tree on the complete graph. Universality conjecture. The main theorem is true for i.i.d. weights (We⃗)e⃗∈E⃗(W_{\vec e})_{\vec e\in\vec E} with continuous distributions supported in (0,∞)(0,\infty). This conjecture proposes that the result is universal over continuous positive-support weight distributions; the supplied text gives no resolution.
