We denote by odd(G) the number of odd degree vertices in a graph G. Theorem 1.2. Let 0 < p < 1 be constant and let G ∼ Gn,p. Then a.a.s. the following hold: (i) G can be decomposed into ⌊∆(G)/2⌋ cycles and a matching of size odd(G)/2. pitbull forest house

Strongly regular graphs and restricted eigenvalues A strongly regular graph G with parameters (v,k,λ,µ) is a non-complete graph on v vertices which is regular with valency k, and which has the property that any two adjacent vertices have λ common neighbours, and any two non-adjacent vertices have µ common neighbours. pitbull for sale in malaysia

WebThe definition is sometimes extended to a decomposition into Hamiltonian cycles for a regular graph of even degree or into Hamiltonian cycles and a single perfect matching for a regular graph of odd degree (Alspach 2010), with a decomposition of the latter type being known as a quasi-Hamilton decomposition (Bosák 1990, p. 123).
