广州特征值反问题AX＝BXA的中心对称解及其最佳逼近

证明了广义特征值反问题AX＝BXA的中心对称解恒存在，给出了其解的一般表达式，给出了解集合中与给定矩阵的最佳逼近解的表达式以及求解最佳逼近解的一个数值算法和一个数值例子。     

An approach to resolving two paradoxes in probability theory

A new mathematical expectation formula with some hypotheses, notions and propositions was givento get rid of the challenge of St. Petersburg paradox and Pascal's wager. Relevant results show that it is veryeffective to apply the model to solve the expected revenue problems containing random events with low proba-bility but high revenue. This work also provides the probability theory with a more widely applied perspectivein group decision-making.
