A Necessary and Suucient Condition for the -coalescent to Come down from Innnity
Let 1 be the standard-coalescent of Pitman, which is deened so that 1 (0) is the partition of the positive integers into singletons, and, if n denotes the restriction of 1 to f1; : : :; ng, then whenever n (t) has b blocks, each k-tuple of blocks is merging to form a single block at the rate b;k , where b;k = Z 1 0 x k?2 (1 ? x) b?k (dx) for some nite measure. We give a necessary and suucient c...
متن کاملConditions for exchangeable coalescents to come down from infinity
An improved condition to come down from infinity for exchangeable coalescent processes with simultaneous multiple collisions of ancestral lineages is provided. For non-critical coalescents this leads to an improved necessary and sufficient condition for the coalescent to come down from infinity. An analog conjecture for the full class of exchangeable coalescents is presented. New examples of cr...
متن کاملA Necessary and Sufficient Condition for Transcendency
As has been known for many years (see, e.g., K. Mahler, /. Reine Angew. Math., v. 166, 1932, pp. 118-150), a real or complex number f is transcendental if and only if the following condition is satisfied. To every positive number co there exists a positive integer n and an infinite sequence of distinct polynomials {p,(z)} = {pr + pr z + • • • + p z } at most of 0 1 n degree n with integral coef...
متن کاملA Necessary and Sufficient Condition for Peace∗
This paper examines the possibility for two contestants to agree on a peace settlement thereby avoiding a contest, in which each would exert a costly effort given the posterior distributions inferred from the negotiation. I find a necessary and sufficient condition of the prior distributions for there to exist a negotiation mechanism that admits a peace-ensuring perfect Bayesian equilibrium. Th...
متن کاملHow do birth and death processes come down from infinity?
We finely describe the "coming down from infinity" for birth and death processes which eventually become extinct. Our biological motivation is to study the decrease of regulated populations which are initially large. Under general assumptions on the birth and death rates, we describe the behavior of the hitting time of large integers. We let two regimes appear and derive an expression of the sp...
