In the table on p. A long-standing conjecture of Stanley states that every Cohen-Macaulay simplicial complex is partitionable. We present a version of the weighted cellular matrix-tree theorem that is suitable for calculating explicit generating functions for spanning trees of highly structured families of simplicial and cell complexes. We study the space X d G of pictures of a graph G in complex projective d -space. We consider three kinds of graph varieties:
Marsh , Dimer models and cluster categories of Grassmannians , Proc. In the disconnected zone, we discuss the number of isolated vertices. Essay on how i help my parents at home. Applications include several formulas some old and some new for evaluations of the Tutte polynomial. Cambridge University Press We introduce a cubical analogue of shiftedness, and obtain a recursive formula for the Laplacian eigenvalues of shifted cubical complexes, in particular, these eigenvalues are also integers.
Much information about a graph can be obtained by studying its spanning trees. Homepage of Man-Wai, Cheung. In addition, we are able to answer many questions about the geometry of the slope variety by translating them into purely combinatorial problems concerning enumeration of trees. Translation between these two kinds of trees can be accomplished by a simple algorithm, which we provide.
