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 ...
Using the ELECTRE MLO Multi-Criteria Decision-Making Method in Stepwise Benchmarking - Application in Higher Education.
(Operational Research in Engineering Sciences: Theory and Applications, 2019)
This paper describes multi-criteria decision making as a tool for stepwise benchmarking. The ELECTRE MLO ranking method is used. I give a mathematical theorem with a proof which is the answer to the question whether it is ...
