A general layered erasure channel has layers indexed by $l\in\{1,\dots,q\}$, and let Theorem $1$ denote the theorem giving an outer bound on its capacity region. The moderate-inter…

Costa's corner-point conjecture. For reliable communication at both receivers, the following should hold: if $R_2\geq C_2-\varepsilon$ for an arbitrary $\varepsilon>0$, then

Convexity conjecture. For the degraded CMLOBCs described above, the capacity region is strictly concave ($\cap$) if and only if
