摘要:

泛函积分是从量子力学、统计热力学到生物学、化学和金融学等现代理论的核心。本文提出一种基于有限元公式的泛函积分计算新方法。该方法比现有方法更加稳健、通用且强大,因而能够支持更复杂的计算,并研究以往无法处理的问题。重要的是,多年来在工程分析和偏微分方程领域发展起来的现有程序、单元库和形函数,均可直接用于这一目的。

英文摘要:

Functional integrals are central to modern theories ranging from quantum mechanics and statistical thermodynamics to biology, chemistry, and finance. In this work we present a new method for calculating functional integrals based on a finite-element formulation. This approach is far more robust, versatile, and powerful than existing methods, thus allowing for more sophisticated computations and the study of problems that could not previously be tackled. Importantly, existing procedures, element libraries and shape functions, which have been developed throughout the years in the context of engineering analysis and partial differential equations, may be directly employed for this purpose.
