On Discrete Spectrum of a Model Graph with Loop and Small Edges

The Maximum Number of Edges in a Strongly Multiplicative Graph

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

A scalable directed graph model with reciprocal edges

A stronger relation exists between two nodes when they each point to one another (reciprocal edge) as compared to when only one points to the other (one-way edge). The proportion of reciprocal edges in a network is a good indicator of how tight the relations among the nodes are. The mutual relations could be an indication of friendship in a graph with social behavior or the information flow in ...

A graph associated to spectrum of a commutative ring

Let $R$ be a commutative ring. In this paper, by using algebraic properties of $R$, we study the Hase digraph of prime ideals of $R$.
