随机过程理论中的符号问题和方法错误

he Stochastic Processes is a theory of applied mathematics that reveals and discusses the quantitative relationship and the changing law of dynamic random phenomena in the objective world. This article first points out the concept problem of using the same function symbol to represent both random variable and sample path in stochastic process theory, resulting in a fundamental change in the connotation and extension of sample path, as well as leading to dislocation of research objects and wrong research methods of sample path. Stochastic processes theoryprovide wrong theories, methods, and tools for the research and analysis of dynamic random phenomena in natural sciences, engineering technology, and social sciences. It not only caused serious paradigm crisis in mathematical finance, but also caused major financial crises.
