On $\g$- and local $\g$-Vectors of the Interval Subdivision
Imran Anwar, Shaheen Nazir
We show that the $\g$-vector of the interval subdivision of a simplicial complex with a nonnegative and symmetric -vector is nonnegative. In particular, we prove that such $\g$-…
The - and -vectors of Interval Subdivisions
Imran Anwar, Shaheen Nazir
The interval subdivision Int of a simplicial complex was introduced by Walker. We give the complete combinatorial description of the entries of the transformation matrices…
An Efficient Algebraic Criterion for Shellability
Imran Anwar, Zunaira Kosar, Shaheen Nazir
In this paper, we give a new and efficient algebraic criterion for the pure as well as non-pure shellability of simplicial complex over [n]. We also give an algebraic character…
Linear Residuals and Gallai-Simplicial Complexes
Imran Anwar, Zunaira Kosar, Shaheen Nazir +1
In this paper, we give a new algebraic criterion for the {\em shellability} of (non-pure) simplicial complex over , shellable in the sense of Björner and Wachs \cite{BW}.…
