چکیده
A complex unit gain graph ( T -gain graph) Φ = G , φ ) is a where the function assigns number to each orientation of an edge and its inverse assigned opposite orientation. balanced if product gains oriented cycle (if any) 1. We propose two notions distance matrices D < max min Φ, for any ordering ‘<’ vertex set. characterize graphs which are independent ordering. show holds standard vertices only same vertices, we call such as compatible graphs. whose cospectral with matrix underlying graph. Besides, introduce notion positively weighted establish equivalent condition balance Acharya's Stanić's spectral criteria deduced consequence. obtain some characterizations in terms matrices. Finally, bipartite every block compatible.

Criteria for Balance in Abelian Gain Graphs
A gain graph (Γ, g, G) is a graph Γ = (V,E) together with a group G, the gain group, and a homomorphism g, the gain function, from the free group F (E) on the edge set E into G. We think of the edges of G as oriented in an arbitrary but fixed way, so that if e is an edge in one direction, then e−1 is the same edge in the opposite direction; thus g(e−1) = g(e)−1. A gain graph is balanced if for ...
متن کاملOn -unit distance graphs
We consider a variation on the problem of determining the chromatic number of the Euclidean plane and define the -unit distance graph to be the graph whose vertices are the points of E, in which two points are adjacent whenever their distance is within of 1. For certain values of we are able to show that the chromatic number is exactly seven. For some smaller values we show the chromatic number...
متن کاملDelayed Feedback Control by Commutative Gain Matrices
The delayed feedback control (DFC) is a control method for stabilizing unstable periodic orbits in nonlinear autonomous differential equations. We give an important relationship between the characteristic multipliers of the linear variational equation around an unstable periodic solution of the equation and those of its delayed feedback equation. The key of our proof is a result about the spect...
متن کاملA Power Efficient Gain Enhancing Technique for Current Mirror
This work introduces a new and simple method for adjusting the gain of current mirror. The major advantage of the proposed architecture is that, unlike the conventional variable gain current mirror, it does not need the change of the biasing current to adjust current gain. Therefore, the power dissipation remains constant in all of the gain settings. In addition, the proposed variable gain curr...
