In this paper we study the cycle descent statistic on permutations. Several involutions on permutations and derangements are constructed. Moreover, we construct a bijection between negative cycle descent permutations and Callan perfect matchings.

Suppose G=(V,E) is a graph with the vertex set V(G) and edge set E(G) we defined a labeling f:V?E?{1,2,…,k} to be an edge irregular total k-labeling of graph G if for every two different edge e and f there is wt(e)?wt(f). The minimum k for which the graph... see more

The purpose of writing this research is to determine the learning outcomes of mathematics learning on the subject matter of the language of sequences and series by using the learning cycle learning model before using the learning cycle learning model (Lec... see more

The excessive consumption of fossil fuels is causing environmental problems, which can be addressed by utilizing renewable energy sources such as hydro energy, biomass, solar heat, geothermal, and waste heat. In particular, the exhaust gas from gasoline e... see more

Background: The Mathematical Working Spaces (MWS) theoretical framework has developed a growing interest in how mathematical modelling is recognised, analysed, and articulated from its theoretical and empirical scopes. Given the articulations identified i... see more

A zonal labeling of a plane graph G is an assignment of the two nonzero elements of the ring Z3 of integers modulo 3 to the vertices of G such that the sum of the labels of the vertices on the boundary of each regio... see more
