Descending plane partitions and rhombus tilings of a hexagon
with triangular hole
It is shown that the descending plane partitions of Andrews
can be geometrically realized as cyclically symmetric rhombus tilings
of a certain
hexagon of which a centrally located
equilateral triangle of side length 2 has been removed.
Thus, the lattice structure for descending plane
partitions, as introduced by Mills, Robbins and Rumsey, allows for an
