未知量为P([0,1])值的函数方程

A functional equation whose unknown is P([0,1]) valued

Giacomo Aletti, Caterina May, Piercesare Secchi

摘要:

本文研究了一个函数方程,它的未知数将欧几里得空间映射到[0,1]上的概率分布空间.在适当的正则性和边界条件下,证明了其解的存在唯一性,证明了其解连续依赖于边界,并刻画了解在[0,1]上扩散的特征.通过不同配筋分布具有相同平均值的随机配筋瓮得到了正则解。函数方程的一般解定义了[0,1]上分布的一个新的参数集合,推广了Beta族。

英文摘要:

We study a functional equation whose unknown maps a Euclidean space into the space of probability distributions on [0,1]. We prove existence and uniqueness of its solution under suitable regularity and boundary conditions, we show that it depends continuously on the boundary datum, and we characterize solutions that are diffuse on [0,1]. A canonical solution is obtained by means of a Randomly Reinforced Urn with different reinforcement distributions having equal means. The general solution to the functional equation defines a new parametric collection of distributions on [0,1] generalizing the Beta family.
