Discrete Galton–Watson chains occur in physics and chemistry in the context of nuclear and chemical chain reactions; in formal language theory, they model the rewrite rules of … Web3 ian. 2024 · In the multi-type case, Pénisson [ 19] has proved that a critical d -type GW process conditioned on the total progeny to be large with a given asymptotic proportion of types converges locally to a multi-type GW process (with a special individual per generation) under the condition that the branching process admits moments of order d+1.
WebWe consider a population-size-dependent multitype Galton-Watson branching pro-cess with d types. The process is a vector-valued Markov chain with state space Ng of all d-dimensional vectors z with non-negative integer coordinates. It is defined recursively by d Z, zJ+i = S XOv)(Z), j = 1,' , d, i-I v-I n = 0, 1,.. , and X()(z) is the number of ...
