Algebraic properties of the coordinate ring of a convex polyomino
The electronic journal of combinatorics, Tome 28 (2021) no. 1
We classify all convex polyominoes whose coordinate rings are Gorenstein. We also give an upper bound for the Castelnuovo-Mumford regularity of the coordinate ring of any convex polyomino in terms of the smallest interval which contains its vertices. We give a recursive formula for computing the multiplicity of a stack polyomino.
