Resolution of Unmixed Bipartite Graphs

Fatemeh Mohammadi, Somayeh Moradi

For an unmixed bipartite graph $G$ we consider the lattice of vertex covers $L_{G}$ and compute depth, projective dimension and extremal Betti-numbers of $R / I (G)$ in terms…

Poincaré series of some hypergraph algebras

Eric Emtander, Ralf Fröberg, Fatemeh Mohammadi +1

A hypergraph $H = (V, E)$ , where $V = {x_{1}, ..., x_{n}}$ and $E \subseteq 2^{V}$ defines a hypergraph algebra $R_{H} = k [x_{1}, ..., x_{n}] / (x_{i_{1}} ... x_{i_{k}}; {i_{1}, ..., i_{k}} \in E)$ . All our hypergr…
