replacement and zig-zag products, cayley graphs and lamplighter random walk
نویسندگان
چکیده
we investigate two constructions - the replacement and the zig-zag product of graphs - describing several fascinating connections with combinatorics, via the notion of expander graph, group theory, via the notion of semidirect product and cayley graph, and with markov chains, via the lamplighter random walk. many examples are provided.

Zig-zag and replacement product graphs and LDPC codes
It is known that the expansion property of a graph influences the performance of the corresponding code when decoded using iterative algorithms. Certain graph products may be used to obtain larger expander graphs from smaller ones. In particular, the zig-zag product and replacement product may be used to construct infinite families of constant degree expander graphs. This paper investigates the...
متن کاملContainment Game Played on Random Graphs: Another Zig-Zag Theorem
We consider a variant of the game of Cops and Robbers, called Containment, in which cops move from edge to adjacent edge, the robber moves from vertex to adjacent vertex (but cannot move along an edge occupied by a cop). The cops win by “containing” the robber, that is, by occupying all edges incident with a vertex occupied by the robber. The minimum number of cops, ξ(G), required to contain a ...
متن کاملUniform Mixing Time for Random Walk on Lamplighter Graphs
Suppose that G is a finite, connected graph and X is a lazy random walk on G. The lamplighter chain X associated with X is the random walk on the wreath product G = Z2 oG, the graph whose vertices consist of pairs (f, x) where f is a labeling of the vertices of G by elements of Z2 and x is a vertex in G. There is an edge between (f, x) and (g, y) in G if and only if x is adjacent to y in G and ...
متن کاملThe zig-zag product
The expander constructions based on algebraic methods can give expanders that are both explicit (i.e. we can quickly construct the graph, or even obtain neighborhood information without constructing the entire graph, and Ramanujan, meaning that the spectral gap is essentially as large as possible. It also follows from this spectral bound that the edge expansion of Ramanujan graphs is essentiall...
متن کاملSOLVABILITY OF FREE PRODUCTS, CAYLEY GRAPHS AND COMPLEXES
In this paper, we verify the solvability of free product of finite cyclic groups with topological methods. We use Cayley graphs and Everitt methods to construct suitable 2-complexes corresponding to the presentations of groups and their commutator subgroups. In particular, using these methods, we prove that the commutator subgroup of $mathbb{Z}_{m}*mathbb{Z}_{n}$ is free of rank $(m-1)(n-1)$ fo...
متن کاملEuler-type Identities for Integer Compositions via Zig-zag Graphs
This paper is devoted to a systematic study of combinatorial identities which assert the equality of different sets of compositions, or ordered partitions, of integers. The proofs are based on properties of zig-zag graphs the graphical representations of compositions introduced by Percy A. MacMahon in his classic book Combinatory Analysis. In particular it is demonstrated, by means of general t...
