Enumeration of lozenge tilings of a hexagon with a maximal staircase and a unit triangle removed

Ranjan Rohatgi

Proctor proved a formula for the number of lozenge tilings of a hexagon with side-lengths $a, b, c, a, b, c$ after removing a "maximal staircase." Ciucu then presented a weighted versio…

Enumeration of lozenge tilings of halved hexagons with a boundary defect

Ranjan Rohatgi

We generalize a special case of a theorem of Proctor on the enumeration of lozenge tilings of a hexagon with a maximal staircase removed, using Kuo's graphical condensation method.…
