A 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 کاملNecessary and sufficient condition on global optimality without convexity and second order differentiability
The main goal of this paper is to give a necessary and sufficient condition of global optimality for unconstrained optimization problems, when the objective function is not necessarily convex. We use Gâteaux differentiability of the objective function and its bidual (the latter is known from convex analysis).
متن کاملA necessary and sufficient minimality condition for uncertain systems
A necessary and sufficient condition is given for the exact reduction of systems modeled by linear fractional transformations (LFT’s) on structured operator sets. This condition is based on the existence of a rank-deficient solution to either of a pair of linear matrix inequalities which generalize Lyapunov equations; the notion of Gramians is thus also generalized to uncertain systems, as well...
متن کاملA Necessary and Sufficient Condition for Peace An Extended Abstract
Under what conditions can potential contestants avoid conflicts through a peace settlement? This question is relevant to real world situations such as international conflicts and pre-litigation negotiations. In the spirit of Myerson and Satterthwaite [4] on bilateral trade, where information asymmetry is the impediment to mutually beneficial negotiation outcomes, a natural approach to address t...
