多元截断矩问题与最大熵

Multivariate truncated moments problems and maximum entropy

Calin-Grigore Ambrozie

摘要:

本文利用某些最大熵-型表示密度的存在性,刻画了无界支撑上多元截断矩问题的Lebesgue可积解的存在性,并讨论了在二元四阶矩情形下它们的逼近问题.

英文摘要:

We characterize the existence of the Lebesgue integrable solutions of the truncated problem of moments in several variables on unbounded supports by the existence of some maximum entropy -- type representing densities and discuss a few topics on their approximation in a particular case, of two variables and 4th order moments.
