We present a combinatorial solution to the problem of determining the number of lozenge tilings of a hexagon with sides a, b+1, b, a+1, b, b+1, with the central unit triangle removed. For a=b, this settles an open problem posed by Propp [7].
Motivated by the enumeration of a class of plane partitions studied by Proctor and by considerations about symmetry classes of plane partitions, we consider the problem of enumerating lozenge tilings of a hexagon with ''maximal staircases'' removed from some of its vertices. The case of one vertex c
We deal with unweighted and weighted enumerations of lozenge tilings of a hexagon with side lengths a, b+m, c, a+m, b, c+m, where an equilateral triangle of side length m has been removed from the center. We give closed formulas for the plain enumeration and for a certain (&1)-enumeration of these l
