Segre powers of posets preserve EL-shellability

Yifei Li, Sheila Sundaram

For a bounded and graded poset $P$ , we show that if $P$ is EL-shellable, then so is its $t$ -fold Segre power $P^{(t)} = P \circ \dots \circ P$ ( $t$ factors), as defined by Björner an…

Homology of Segre powers of Boolean and subspace lattices

Yifei Li, Sheila Sundaram

Segre products of posets were defined by Björner and Welker (2005). We investigate the homology representations of the $t$ -fold Segre power $B_{n}^{(t)}$ of the Boolean lattice $B_{n}$ …

Topology of Cut Complexes II

Margaret Bayer, Mark Denker, Marija Jelić Milutinović +2

We continue the study of the $k$ -cut complex $Δ_{k} (G)$ of a graph $G$ initiated in the paper of Bayer, Denker, Jelić Milutinović, Rowlands, Sundaram and Xue [Topology of cut complex…
