On the Algebraic Properties of r-circulant Matrices Associated with Generalized k-Pell-Tribonacci Numbers
Marko Pešović, Sonja Telebaković Onić
This study examines the properties of an r-circulant matrix whose entries are defined by the generalized k-Pell-Tribonacci sequence {P_k,n}. Explicit expressions are derived for th…

Integer points enumerator of hypergraphic polytopes
Marko Pesovic
For a hypergraphic polytope there is a weighted quasisymmetric function which enumerates positive integer points in its normal fan and determines its f-polynomial. This quasisymmet…

Weighted quasisymmetric enumerator for generalized permutohedra
Vladimir Grujić, Marko Pešović, Tanja Stojadinović
We introduce a weighted quasisymmetric enumerator function associated to generalized permutohedra. It refines the Billera, Jia and Reiner quasisymmetric function which also include…
