Contiguous Sphere Clusters. I. Isomorphic Chains
One of the remarkable phenomena (still unexplained) concomitant with the transmission of the "code of heredity" to succeeding generations (in sexually reproducing organisms) is "pairing" of the chromosomes at zygotene: That is, during the zygotene stage of meiosis (the process whereby the sex cells are formed) homologous chromosomes become "contiguous" at homologous sites (the chromomers) throu...
متن کاملIsomorphic Factorisations . I : Complete Graphs
An isomorphic factorisation of the complete graph Kj, is a partition of the lines of Kp into t isomorphic spanning subgraphs G; we then write G\Kj, and G G K^/t. If the set of graphs Ky/t is not empty, then of course t\p(p — l)/2. Our principal purpose is to prove the converse. It was found by Laura Guidotti that the converse does hold whenever (/,/>) » 1 or (t,p — 1) «= 1, We give a new and sh...
متن کاملMaximal Chains of Isomorphic Subgraphs of the Rado Graph
The partial order 〈E(R) ∪ {∅},⊂〉, where E(R) is the set of isomorphic subgraphs of the Rado graph R, is investigated. The order types of maximal chains in this poset are characterized as the order types of compact sets of reals having the minimum non-isolated. 2000 Mathematics Subject Classification: 05C80, 06A05, 06A06.
متن کاملMaximal Chains of Isomorphic Suborders of Countable Ultrahomogeneous Partial Orders
We investigate the poset 〈P(X) ∪ {∅},⊂〉, where X is a countable ultrahomogeneous partial order and P(X) the set of suborders of X isomorphic to X. For X different from (resp. equal to) a countable antichain the order types of maximal chains in 〈P(X) ∪ {∅},⊂〉 are characterized as the order types of compact (resp. compact and nowhere dense) sets of reals having the minimum non-isolated. 2000 Math...
متن کاملMaximal Chains of Isomorphic Subgraphs of Countable Ultrahomogeneous Graphs
For a countable ultrahomogeneous graph G = 〈G, ρ〉 let P(G) denote the collection of sets A ⊂ G such that 〈A, ρ ∩ [A]〉 ∼= G. The order types of maximal chains in the poset 〈P(G) ∪ {∅},⊂〉 are characterized as: (I) the order types of compact sets of reals having the minimum nonisolated, if G is the Rado graph or the Henson graph Hn, for some n ≥ 3; (II) the order types of compact nowhere dense set...
