Robin semigroup trace convergence conjecture

Let chatKnw(t)chat K^w_n(t) and chatKw(t)chat K^w(t) be the random and limiting Robin semigroups from Theorem. For every t1,,tk>0t_1,\ldots,t_k>0, Trace convergence conjecture.

limn(Tr[K^nw(ti)])1ik=(Tr[K^w(ti)])1ik\lim_{n\to\infty}\big(\operatorname{Tr}[\hat K^w_n(t_i)]\big)_{1\leq i\leq k}=\big(\operatorname{Tr}[\hat K^w(t_i)]\big)_{1\leq i\leq k}

in joint distribution and mixed moments. This conjectures the trace convergence absent from the Robin semigroup convergence theorem; the source gives no resolution status.
