On the $f$ -vectors of $r$ -multichain subdivisions

Shaheen Nazir

For a poset $P$ and an integer $r \geq 1$ , let $P_{r}$ be a collection of all $r$ -multichains in $P$ . Corresponding to each strictly increasing map $ı : [r] \to [2 r]$ , there is a…

On the homeomorphism and homotopy type of complexes of multichains

Shaheen Nazir, Volkmar Welker

In this paper we define and study for a finite partially ordered set P a class of simplicial complexes on the set P_r of r-element multichains from P. The simplicial complexes depe…

Generalizations of Nekrasov-Okounkov Identity

Amer Iqbal, Shaheen Nazir, Zahid Raza +1

Nekrasov-Okounkov identity gives a product representation of the sum over partitions of a certain function of partition hook length. In this paper we give several generalizations o…
