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 ...

Between graphical zonotope and graph-associahedron
(Turkish Journal of Mathematics, 2023)
This manuscript introduces a finite collection of generalized permutohedra associated to a simple graph. The first polytope of this collection is the graphical zonotope of the graph and the last is the graph–associahedron ...
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 ...
Еxtended Schatten norms of random graphs and Nikiforov conjecture
(Hacettepe University, 2022)
In this paper we give a geometric mean and mean of
p-th degree of singular values for almost all graphs. We prove three
theorems about a conjecture of V. Nikiforov for Schatten p-norm
of graphs when p > 2. We prove that ...
Future Drought Propagation through the Water-Energy-Food-Ecosystem Nexus – a Nordic Perspective
(Elsevier, 2022)
Droughts can affect a multitude of public and private sectors, with impacts developing slowly over time. While droughts are traditionally quantified in relation to the hydrological components of the water cycle that they ...
Water softening by nanofiltration – Case study
(The Serbian Water Pollution Control Society, 2019)
In this research the object of the analysis was the improvement of drinking water treatment plant, while groundwater being a source of drinking water.
Improvements include the removal of magnesium and manganese. Improvements ...
