Hilbert series of Parallelogram Polyominoes

Ayesha Asloob Qureshi, Giancarlo Rinaldo, Francesco Romeo

We present a conjecture about the reduced Hilbert series of the coordinate ring of a simple polyomino in terms of particular arrangements of non-attacking rooks that can be placed…

Chordal circulant graphs and induced matching number

Francesco Romeo

Let $G = C_{n} (S)$ be a circulant graph on $n$ vertices. In this paper we characterize chordal circulant graphs and then we compute $ν (G)$ , the induced matching number of $G$ . These…

On the reduced Euler characteristic of independence complexes of circulant graphs

Giancarlo Rinaldo, Francesco Romeo

Let $G$ be the circulant graph $C_{n} (S)$ with $S \subseteq {1, \dots, ⌊ \frac{n}{2} ⌋}$ . We study the reduced Euler characteristic $χ ~$ of the independen…
