高阶导数场论的研究

Investigations In Higher Derivative Field Theories

Biswajit Paul

摘要:

规范分析导致正式量化的高阶导数理论被认为是。采用一阶形式主义,所有的配置空间变量以及它们的高阶时间导数被认为是独立的领域。本文发展了一个系统的独立规范对称性的抽象算法,它是Banerjee等人为通常的一阶理论所发展的方法的推广。对于具有曲率的相对论性粒子模型,我们解决了独立规范参数个数与独立初级第一类约束个数的不匹配问题。此外,我们还证明了刚性相对论粒子的规范对称性与$W_3$ -代数之间的直接联系。此外,BRST对称性的质量和无质量粒子模型已被认为是其连接到$W_3$ -代数证明。这种规范对称性的精确映射与重参数化不变性。从场论,重力和膜理论的不同模型已被视为说明性的例子,从一个新的角度来澄清许多没有得到充分解决的问题。

英文摘要:

Canonical analysis leading to formal quantisation of the higher derivative theories are considered. The first order formalism is adopted where all the configuration space variables along with their higher time derivatives are considered to be independent fields. A systematic algorithm of abstracting the independent gauge symmetries is developed which is an extension of the method developed by Banerjee et al. for the usual first order theories. For the massive relativistic particle model with curvature, we solve the mismatch in the no of independent gauge parameters and no of independent primary fist class constarints. In addition, we show a direct connection between the gauge symmetry and the $W_3$-algebra for the rigid relativistic particle. Also, BRST symmetries for both the massive and massless particle models have been considered and its connection to $W_3$-algebras is demonstrated. The exact mapping of this gauge symmetry is shown with the reparametrisation invariance. Different models from field theory, gravity and membrane theory have been considered as illustrative examples from a new perspective to clarify many not so adequately addressed issues.
