扩展概率:数学基础

Extended Probabilities: Mathematical Foundations

Mark Burgin

摘要:

物理学中有许多重要的问题与概率的概念有关。其中一个问题与20世纪30年代物理学中使用的负概率有关。尽管有许多证明负概率有用的例子,物理学家还是带着怀疑的眼光看待它们,试图在他们的理论中避免这个新概念。困扰物理学家的主要问题是数学基础和对负概率的解释。本文引入扩展概率作为概率函数,它可以取正值和负值。用公理化的方法定义了广义概率,证明了经典概率是广义概率的正截面。

英文摘要:

There are important problems in physics related to the concept of probability. One of these problems is related to negative probabilities used in physics from 1930s. In spite of many demonstrations of usefulness of negative probabilities, physicists looked at them with suspicion trying to avoid this new concept in their theories. The main question that has bothered physicists is mathematical grounding and interpretation of negative probabilities. In this paper, we introduce extended probability as a probability function, which can take both positive and negative values. Defining extended probabilities in an axiomatic way, we show that classical probability is a positive section of extended probability.
