ab: Summary: A rate-distortion problem is considered for a triangular
    communication system (TCS) which has one encoder $f$ and two decoders
    $g_X$ and $g_Y$. The encoder $f$ maps correlated source outputs $(X^K,
    Y^K)$ to two codewords $W_X$ and $W_Y$, which are sent to $g_X$ and
    $g_Y$, respectively. The decoders $g_X$ and $g_Y$ can communicate with
    each other via rate-constrained channels as many times as they need,
    and $g_X$ reproduces $\widehat X^K$ while $g_Y$ reproduces $\widehat
    Y^K$. The admissible rate-distortion region is determined for this TCS.
    Furthermore, the relations between the TCS and the Gray-Wyner system,
    Wyner’s common information, Yamamoto’s cascade communication
    system, and the successive refinement system are discussed.
