WebAbstract : The report presents one short inductive proof which characterizes, by construction, both the minimally 2-connected graphs and the minimally strong digraphs. Several operations are given which can be used to construct minimally strong digraphs from other minimally strong digraphs and then, by straightforward modifications, these … WebApr 13, 2024 · The graphs show that the magnetic hysteresis loops of pure CuFe 2 O 4 ferrites, different compositions of graphene with copper ferrite, and pure graphene samples exhibit an s-like trend, indicating a solid magnetic reaction to a changing magnetic field (Tang et al., 2024), due to an external magnetic field (the 20S). WebThe main purpose of this paper is to provide some further characterizations of outerplanar graphs. A graph G = (V, E) consists of a set V of n vertices and a set E of m edges.
