Spielman October 22, 2018 15.1 Overview We prove Tutte’s theorem [Tut63], which shows how to use spring embeddings to obtain planar drawings of 3-connected planar graphs. In mathematics, spectral graph theory is the study of the properties of a graph in relationship to the characteristic polynomial, eigenvalues, and eigenvectors of matrices associated with the graph, such as its adjacency matrix or Laplacian matrix. hypercubes, The Design of Approximation Algorithms by David P. Williamson and David B. Shmoys. CPSC 462/562 is the latest incarnation of my course course on Spectral Graph Theory.

Our number of spanning trees for spectral sparsiﬁer matches the number of spanning trees required to obtain a cut sparsiﬁer in [Fung, Hariharan, Harvey, Panigraphi STOC 11]. In particular, most graph distances consider that the nodes are exchangeable—ignoring node “identities.” Alignment of the graphs according to identified nodes enables us to enhance these distances’ sensitivity to perturbations in the network and detect important changes in graph dynamics. 16; Spielman Ch.7 whiteboard, scribe notes ps1, due 9/25 (pdf, tex) 2. �5�l�e}��/�=�c�0�1ߙn���W6{2\�)�V�~ ���9�r����/�Əj���mz��*������3�ڶxc��8Y~7�#}}�Q�c�>��6.���'�i4�e^�r��!�8�!/�Kx-�2�U���X@�Y�u]v�Yu��:�Q��|�^����:��[PS�������A,|M�9���8��_G5�C�K�ݮlp�\u���!LMS|slT������\mܮ�~�طQ]�L3c. not have time to cover in class.
