Jan 25, 2018 · Abstract In this paper, we obtain sharp lower and upper bounds for the spectral radius of a barbell graph by considering the principal vector.Moreover, we present the characteristic polynomial and spectral radius equations of the graph by some vital relational expressions in An Introduction to the Theory of Graph Spectra.
Atomic radii decrease from left to right across a period and increase from top to bottom along a Predict the relative atomic sizes of the elements based on the general trends in atomic radii for the...
For the radius problem, Berman and Kasiviswanathan  showed that the approach of Aingworth et al. can be used to obtain in O˜(m √ n+ n2) time an estimate ˆr that satisﬁes r ≤ rˆ ≤ 3/2r, where r is the radius of the graph. Thus both radius and diameter admit O˜(m √ n + n2) time 3/2-approximations.
Type Package Title A Tidy API for Graph Manipulation Version 1.2.0 Maintainer Thomas Lin Pedersen Description A graph, while not ``tidy'' in itself, can be thought of as two tidy.
A line graph is especially helpful in showing recurring data to facilitate comparison. For instance, repeated experiments in the field of science or other subjects, tables used are not intuitive enough to...

radius of graphs: Given a set Gof graphs, nd an upper bound for the spectral radius over all graphs of G, and characterize the graphs in which the supremum spectral radius is attained. Inspired by this problem, the eigenvalues of special classes of graphs are well studied in the literature, such as graphs with given chromatic number
