Let $G=G(W_n)$ and let $\psi,\psi'\in\Psi^+(G_n)$ be local Arthur parameters with $\psi\geq_C\psi'$. Suppose that $\pi\in\Pi_\psi\cap\Pi_{\psi'}$. The closure-monotonicity conjectu…

Closure ordering conjecture. For every $pi e Pipsi$, one has

Maximal and minimal parameter conjecture. For any $\psi1,\psi2 e \Psi(pi)$, one has $\lambda{\phi{\psi1}}=\lambda{\phi{\psi2}}$. Moreover, there are unique…
