论文摘要
引入了一种在平坦时空中研究非同性骨弦的新方法，基于对弦的最小作用的整体汉密尔顿分析。但是，这导致了一种结构上的新形式，该形式与已知结果相当，因为在适当的限制下，它在最小动作（Nambu Goto型）之间进行了插值，在该动作（Nambu Goto Type）中，弦指标被认为是由嵌入式和Polyakov类型的动作引起的，而世界板组成部分是独立的。通过使用约束分析对对称性进行详细研究，建立了不同动作之间的等效性。阐明了现有文献中各种烦恼的问题。此处介绍的插值作用显示出揭示字符串的几何形状，并且可能在分析非依次的弦线和弯曲背景时很有用。
A new approach to the study of nonrelativistic bosonic string in flat space time is introduced, basing on a holistic hamiltonian analysis of the minimal action for the string. This leads to a structurally new form of the action which is, however, equivalent to the known results since, under appropriate limits, it interpolates between the minimal action (Nambu Goto type) where the string metric is taken to be that induced by the embedding and the Polyakov type of action where the world sheet metric components are independent fields. The equivalence among different actions is established by a detailed study of symmetries using constraint analysis. Various vexing issues in the existing literature are clarified. The interpolating action mooted here is shown to reveal the geometry of the string and may be useful in analyzing nonrelativistic string coupled with curved background.
