基本zeta函数及其在物理学中的应用

Basic zeta functions and some applications in physics

Klaus Kirsten

摘要:

这些讲座的目的是介绍一些基本的zeta函数及其在卡西米尔效应和玻色-爱因斯坦凝聚领域的应用。有关各节对这些领域作了简要介绍。我们将专门考虑谱zeta函数,即zeta函数产生于适当的微分算子的本征值谱。有一组技术工具是理解基本上每个光谱zeta函数的分析性质的核心。这些工具介绍了使用的赫维茨,爱泼斯坦和巴恩斯zeta函数的充分研究的例子。它解释了这些不同的例子zeta函数都可以被认为是由相同的机制产生的,即它们都是由合适的(偏)微分算子的特征值产生的。正是这种与偏微分算子的关系提供了分析这些讲座中考虑的zeta函数的动机。例如,动机来自于“人们能听到鼓的形状吗?卡西米尔效应对边界有什么认识?".最后,“玻色气体对它的容器了解多少?"

英文摘要:

It is the aim of these lectures to introduce some basic zeta functions and their uses in the areas of the Casimir effect and Bose-Einstein condensation. A brief introduction into these areas is given in the respective sections. We will consider exclusively spectral zeta functions, that is zeta functions arising from the eigenvalue spectrum of suitable differential operators. There is a set of technical tools that are at the very heart of understanding analytical properties of essentially every spectral zeta function. Those tools are introduced using the well-studied examples of the Hurwitz, Epstein and Barnes zeta function. It is explained how these different examples of zeta functions can all be thought of as being generated by the same mechanism, namely they all result from eigenvalues of suitable (partial) differential operators. It is this relation with partial differential operators that provides the motivation for analyzing the zeta functions considered in these lectures. Motivations come for example from the questions "Can one hear the shape of a drum?" and "What does the Casimir effect know about a boundary?". Finally "What does a Bose gas know about its container?"
