The Kirchhoff's Matrix-Tree Theorem revisited: counting spanning trees with the quantum relative entropy
نویسندگان
چکیده
By revisiting the Kirchhoff’s Matrix-Tree Theorem, we give an exact formula for the number of spanning trees of a graph in terms of the quantum relative entropy between the maximally mixed state and another state specifically obtained from the graph. We use properties of the quantum relative entropy to prove tight bounds for the number of spanning trees in terms of basic parameters like degrees and number of vertices.

A formula for the number of spanning trees in circulant graphs with non-fixed generators∗
We consider the number of spanning trees in circulant graphs of βn vertices with generators depending linearly on n. The matrix tree theorem gives a closed formula of βn factors; while we derive a formula of β−1 factors. The spanning tree entropy of these graphs is then compared to the one of fixed generated circulant graphs.
متن کاملCounting the number of spanning trees of graphs
A spanning tree of graph G is a spanning subgraph of G that is a tree. In this paper, we focus our attention on (n,m) graphs, where m = n, n + 1, n + 2, n+3 and n + 4. We also determine some coefficients of the Laplacian characteristic polynomial of fullerene graphs.
متن کاملThe Contraction Method for Counting the Complexity of Planar Graphs with Cut Vertices
In this paper, we investigate the number of spanning trees in planar graphs with two cut vertices. We propose a combinatorial approach based on the contraction method, in order to derive spanning trees recursions for this class of graphs. Applications on different graphs showed the efficiency and the simplicity of our recursive approach in comparison with the classic matrix tree theorem. Mathem...
متن کاملA Weighted Cellular Matrix-tree Theorem, with Applications to Complete Colorful and Cubical Complexes
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 apply the result to give weighted generalizations of the tree enumeration formulas of Adin for complete colorful complexes, and of Duval, Klivans and Martin for skeleta of hypercubes...
متن کاملLOCAL CHARACTERISTICS, ENTROPY AND LIMIT THEOREMS FOR SPANNING TREES AND DOMINO TILINGS VIA TRANSFER-IMPEDANCES Running Head: LOCAL BEHAVIOR OF SPANNING TREES
Let G be a finite graph or an infinite graph on which ZZ acts with finite fundamental domain. If G is finite, let T be a random spanning tree chosen uniformly from all spanning trees of G; if G is infinite, methods from [Pem] show that this still makes sense, producing a random essential spanning forest of G. A method for calculating local characteristics (i.e. finite-dimensional marginals) of ...
