Expander Graphs
This paper will introduce expander graphs. Kolmogorov and Barzdin’s proof on the three dimensional realization of networks will be discussed as one of the first examples of expander graphs. The last section will discuss error correcting code as an application of expander graphs to computer science.

متن کاملInfection of Tissue Expander With Candida Parapsilosis
A 13-month-old boy underwent placement of a tissue expander in the subgaleal plane in the forehead. The indication for skin expansion was a large congenital melanocytic nevus involving the forehead and glabella. Serial inflations of the expander were performed in the plastic surgery clinic using sterile equipment. Alcohol was used to prepare the skin overlying the injection port. Three months f...
متن کاملExpander Graphs
Let AG be the adjacency matrix of G. Let λ1 ≥ λ2 ≥ . . . ≥ λn be the eigenvalues of AG. Sometimes we will also be interested in the Laplacian matrix of G. This is defined to be LG = D−AG, where D is the diagonal matrix where Dvv equals the degree of the vertex v. For d-regular graphs, LG = dI −AG, and hence the eigenvalues of LG are d− λ1, d− λ2, . . . , d− λn. Lemma 1. • λ1 = d. • λ2 = λ3 = . ...
متن کاملExpander Codes
We present a new class of asymptotically good, linear error-correcting codes based upon expander graphs. These codes have linear time sequential decoding algorithms , logarithmic time parallel decoding algorithms with a linear number of processors, and are simple to understand. We present both randomized and explicit constructions for some of these codes. Experimental results demonstrate the ex...
