Site percolation on pseudo‐random graphs

چکیده
We consider vertex percolation on pseudo-random d $$ -regular graphs. The previous study by the second author established existence of phase transition from small components to a linear (in n \frac{n}{d} ) sized component, at p = 1 p=\frac{1}{d} . In supercritical regime, our main result recovers sharp asymptotic size largest and shows that all other are typically much smaller. Furthermore, we typical properties component such as number edges, long cycle expansion. subcritical strengthen upper bound likely size.

Quantum Site Percolation on Amenable Graphs
We consider the quantum site percolation model on graphs with an amenable group action. It consists of a random family of Hamiltonians. Basic spectral properties of these operators are derived: non-randomness of the spectrum and its components, existence of an self-averaging integrated density of states and an associated trace-formula.
متن کاملThe Phase Transition in Site Percolation on Pseudo-Random Graphs
We establish the existence of the phase transition in site percolation on pseudo-random dregular graphs. Let G = (V,E) be an (n, d, λ)-graph, that is, a d-regular graph on n vertices in which all eigenvalues of the adjacency matrix, but the first one, are at most λ in their absolute values. Form a random subset R of V by putting every vertex v ∈ V into R independently with probability p. Then f...
متن کاملPseudorandom graphs
A pseudorandom graph is a graph that behaves like a random graph of the same edge density. For example, it might be the case that the graph has roughly the same edge density between any two large sets or that it contains roughly the same number of copies of every small graph H as one would expect to find in a random graph. The purpose of this course will be to explore certain notions of pseudor...
متن کاملAlgebraic Connectivity Under Site Percolation in Finite Weighted Graphs
We study the behavior of algebraic connectivity in a weighted graph that is subject to site percolation, random deletion of the vertices. Using a refined concentration inequality for random matrices we show in our main theorem that the (augmented) Laplacian of the percolated graph concentrates around its expectation. This concentration bound then provides a lower bound on the algebraic connecti...
متن کاملPercolation on Finite Cayley Graphs
In this paper, we study percolation on finite Cayley graphs. A conjecture of Benjamini says that the critical percolation pc of any vertex–transitive graph satisfying a certain diameter condition can be bounded away from one. We prove Benjamini’s conjecture for some special classes of Cayley graphs. We also establish a reduction theorem, which allows us to build Cayley graphs for large groups w...
