Rhombus Tilings of a Hexagon with Two Triangles Missing on the Symmetry Axis
Theresia Eisenkölbl
We compute the number of rhombus tilings of a hexagon with sides n, n, N, n, n, N, where two triangles on the symmetry axis touching in one vertex are removed. The case of the comm…

Rhombus Tilings of a Hexagon with Three Fixed Border Tiles
Theresia Eisenkölbl
We compute the number of rhombus tilings of a hexagon with sides with three fixed tiles touching the border. The particular case solves a problem…
