Extendable shellability for $d$-dimensional complexes on $d+3$ vertices


الملخص بالإنكليزية

We prove that for all $d geq 1$ a shellable $d$-dimensional simplicial complex with at most $d+3$ vertices is extendably shellable. The proof involves considering the structure of `exposed edges in chordal graphs as well as a connection to linear quotients of quadratic monomial ideals.
