New results on edge-bandwidth

چکیده
The edge-bandwidth problem is an analog of the classical bandwidth problem, in which one has to label the edges of a graph by distinct integers such that the maximum difference of labels of any two incident edges is minimized. We prove tight bounds on the edge-bandwidth of hypercube and butterfly graphs and complete k-ary trees which extend and improve on previous known results. We also provide an improvement on the upper bound for the bandwidth of butterfly.

Edge-bandwidth of grids and tori
The edge-bandwidth of a graph G is the smallest number B ′ for which there is a bijective labeling of E(G) with {1, . . . , e(G)} such that the difference between the labels at any adjacent edges is at most B ′. Here we compute the edge-bandwidth for rectangular grids: B ′(Pm Pn)= 2min(m, n)− 1 if max(m, n) 3, where is the Cartesian product and Pn denotes the path on n vertices. This settles a ...
متن کاملOn the bandwidth of Mobius graphs
Bandwidth labelling is a well known research area in graph theory. We provide a new proof that the bandwidth of Mobius ladder is 4, if it is not a $K_{4}$, and investigate the bandwidth of a wider class of Mobius graphs of even strips.

One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...
متن کاملDesign of a new narrow band channel drop filter based on photonic crystal ring resonator
In this design an optical ring resonator are embedded between two Horizontal input and output waveguides which has 4 orbitals around the center of the resonator so that each orbital consists of 8 rods with different size in which radius of larger orbitals rods are bigger than radius of smaller orbitals rods. The analysis of simulation results showed the proposed filter has the transmission effi...
