Regularities on the Cayley Graphs of Groups of Linear Growth
Let G be a finitely generated group and E 5 E 1 < E 2 1 a finite generating system . Define the E -length l E ( g ) of g P G as the minimum length of a representation of g as a product of elements in E , and define f E ( n ) as the number of elements in G with E -length equal to n . We will say that a finitely generated group has polynomial growth if there exists an integer k such that f E ( n ...
متن کاملQuantum Graphs I. Some Basic Structures
We use the name “quantum graph” for a graph considered as a one-dimensional singular variety and equipped with a self-adjoint differential (in some cases pseudo-differential) operator (“Hamiltonian”). There are manifold reasons for studying quantum graphs. They naturally arise as simplified (due to reduced dimension) models in mathematics, physics, chemistry, and engineering (nanotechnology), w...
متن کاملIdeal Whitehead graphs in Out(Fr). I. Some unachieved graphs
Masur and Smillie, 1993, proved precisely which singularity index lists arise from pseudo-Anosov mapping classes. In search of an analogous theorem for outer automorphisms of free groups, Handel and Mosher, 2011, ask: Is each connected, simplicial, (2r − 1)-vertex graph the ideal Whitehead graph of a fully irreducible φ ∈ Out(Fr)? We answer this question in the negative by exhibiting, for each ...
متن کاملOn vertex balance index set of some graphs
Let Z2 = {0, 1} and G = (V ,E) be a graph. A labeling f : V → Z2 induces an edge labeling f* : E →Z2 defined by f*(uv) = f(u).f (v). For i ε Z2 let vf (i) = v(i) = card{v ε V : f(v) = i} and ef (i) = e(i) = {e ε E : f*(e) = i}. A labeling f is said to be Vertex-friendly if | v(0) − v(1) |≤ 1. The vertex balance index set is defined by {| ef (0) − ef (1) | : f is vertex-friendly}. In this paper ...
متن کاملA study on some properties of leap graphs
In a graph G, the first and second degrees of a vertex v is equal to thenumber of their first and second neighbors and are denoted by d(v/G) andd 2 (v/G), respectively. The first, second and third leap Zagreb indices are thesum of squares of second degrees of vertices of G, the sum of products of second degrees of pairs of adjacent vertices in G and the sum of products of firs...
