A Simple Explicit Bijection Between (n,2)-Gog and Magog Trapezoids
A sub-problem of the open problem of finding an explicit bijection between alternating sign matrices and totally symmetric self-complementary plane partitions consists in finding an explicit bijection between so-called (n,k)-Gog trapezoids and (n,k)-Magog trapezoids. A quite involved bijection was found by Biane and Cheballah in the case k=2. We give here a simpler bijection for this case.
