The chromatic number of a graph G, denoted by χ(G), is the minimum number of colors such that G can be colored with these colors in such a way that no two adjacent vertices have the same color. A clique in a graph is a set of mutually adjacent vertices. The maximum size of a clique in a graph G is called the clique number of G. The Turán graph Tn(k) is a complete k-partite graph whose partition...

In this paper, we study both concepts of geodetic dominatingand edge geodetic dominating sets and derive some tight upper bounds onthe edge geodetic and the edge geodetic domination numbers. We also obtainattainable upper bounds on the maximum number of elements in a partitionof a vertex set of a connected graph into geodetic sets, edge geodetic sets,geodetic domin...

in the mathematical analysis, there are some theorems and definitions that established for both real and fuzzy numbers. in this study, we try to prove  bernoulli's inequality in fuzzy real numbers with some of its applications. also, we prove two other theorems in fuzzy real numbers which are proved before, for real numbers.

Positive coupling effect in gas condensate reservoirs is assessed through a pure theoretical approach. A combination of linear stability analysis and long bubble approximation is applied to describe gas condensate coupled flow and relative permeability, thereof. The role of capillary number in gas condensate flow is clearly expressed through closed formula for relative permeability. While the m...

This study aims to determine how much influence the Literacy Rate and Life Expectancy on Poverty Levels in Provinces of Aceh, West Java, DKI Yogyakarta, East Java 2015-2021. The method used is a quantitative method. Data obtained from Central Statistics Agency processed by author using E-views 9 application help obtain conclusions. one fundamental problems, because poverty involves meeting most...

We describe a family of graphs with queue-number at most 4 but unbounded stack-number. This resolves open problems Heath, Leighton and Rosenberg (1992) Blankenship Oporowski (1999).
