Approximate Edge Splitting
نویسنده
چکیده
We show that, in any undirected graph, splitting-off can be performed while preserving all cuts of value at most 4/3 times the minimum value, and this is the best possible. This generalizes a classical splitting-off result of Lovász.

Perfect Matchings in Edge-Transitive Graphs
We find recursive formulae for the number of perfect matchings in a graph G by splitting G into subgraphs H and Q. We use these formulas to count perfect matching of P hypercube Qn. We also apply our formulas to prove that the number of perfect matching in an edge-transitive graph is , where denotes the number of perfect matchings in G, is the graph constructed from by deleting edges with an en...

متن کاملEdge Detection with Hessian Matrix Property Based on Wavelet Transform
In this paper, we present an edge detection method based on wavelet transform and Hessian matrix of image at each pixel. Many methods which based on wavelet transform, use wavelet transform to approximate the gradient of image and detect edges by searching the modulus maximum of gradient vectors. In our scheme, we use wavelet transform to approximate Hessian matrix of image at each pixel, too. ...
متن کاملEdge Detection by Adaptive Splitting II. The Three-Dimensional Case
In Lianas and Lantaron, J. Sci. Comput. 46, 485-518 (2011) we proposed an algorithm (EDAS-<i) to approximate the jump discontinuity set of functions defined on subsets of R. This procedure is based on adaptive splitting of the domain of the function guided by the value of an average integral. The above study was limited to the ID and 2D versions of the algorithm. In this paper we address the th...
متن کاملA Simple Approach for Shallow-Water Solitary Wave Interactions
This paper presents analysis of the nonlinear interaction of a pair of solitary waves, the splitting of an isolated hump into a train of solitary waves, and the fission of a single solitary wave on reaching a shelf. Such interactions and splitting behaviour are usually described in the Korteweg–de Vries equation using the Hirota method, or more generally in terms of inverse scattering, a type o...
