Weighted P-partitions enumerator
(Applicable Analysis and Discrete Mathematics, 2021)
To an extended generalized permutohedron we associate the weighted integer points enumerator, whose principal specialization is the f-polynomial. In the case of poset cones it refines Gessel's P-partitions enumerator. We ...
Integer points enumerator of hypergraphic polytopes
(Mathematical Institute of the Serbian Academy of Sciences and Arts, 2021)
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 quasisymmetric function
invariant of hypergraphs ...
A Note on the Generalized Narayana’s Cows Sequence
(XI simpozijum "Matematika i primene", 2021)
The importance of integer sequences as well as structured matrices and their applications, motivated us to explore this topic. In particular, the Narayana’s cows sequence, which is closely related to the Fibonacci sequence, ...
