Approximation for extinction probability of the contact process based on the Gröbner basis

In this note we give a new method for getting a series of approximations for the extinction probability of the one-dimensional contact process by using the Gröbner basis.

Bounds on the Extinction Time Distribution of a Branching Process

The class of fractional linear generating functions, one of the few known classes of probability generating functions whose iterates can be explicitly stated, is examined. The method of bounding a probability generating function g (satisfying g"(1)< oo) by two fractional linear generating functions is used to derive bounds for the extinction time distribution of the Galton-Watson branching proc...

On ‎c‎omputing the general Narumi-Katayama index of some ‎graphs

‎The Narumi-Katayama index was the first topological index defined‎ ‎by the product of some graph theoretical quantities‎. ‎Let $G$ be a ‎simple graph with vertex set $V = {v_1,ldots‎, ‎v_n }$ and $d(v)$ be‎ ‎the degree of vertex $v$ in the graph $G$‎. ‎The Narumi-Katayama ‎index is defined as $NK(G) = prod_{vin V}d(v)$‎. ‎In this paper,‎ ‎the Narumi-Katayama index is generalized using a $n$-ve...

The Contact Process on Trees

The contact process on an infinite homogeneous tree is shown to exhibit at least two phase transitions as the infection parameter λ is varied. For small values of λ a single infection eventually dies out. For larger λ the infection lives forever with positive probability but eventually leaves any finite set. (The survival probability is a continuous function of λ, and the proof of this is much ...
