标题： A Model for Classical Space-time Co-ordinates

摘要： 具有广义协变性的场方程被解释为描述物理时空坐标的目标空间方程，这些方程是基于具有共形不变性的底空间来表述的。 这些方程允许有无限多个非等价的拉格朗日描述。 通过在这些考虑中反转底空间和目标空间变量的角色，可以得到一个重参数化不变膜的模型。 显示英文摘要

摘要： Field equations with general covariance are interpreted as equations for a target space describing physical space time co-ordinates, in terms of an underlying base space with conformal invariance. These equations admit an infinite number of inequivalent Lagrangian descriptions. A model for reparametrisation invariant membranes is obtained by reversing the roles of base and target space variables in these considerations.
