我们提出了一个狭义相对论的修正，其中的物理能量，这可能是普朗克能量，加入光速作为一个不变量，尽管一个完整的相对论的惯性系和协议爱因斯坦的理论在低能量。这是通过对洛伦兹群在动量空间中的作用进行非线性修正来实现的，这种修正是通过在每一次助推中增加一个膨胀来产生的，以使普朗克能量保持不变。关联代数具有未修改的结构常数。我们还讨论了由此产生的修改场论，并建议修改的等效原理，它决定了新的理论是如何嵌入在广义相对论。
We propose a modification of special relativity in which a physical energy, which may be the Planck energy, joins the speed of light as an invariant, in spite of a complete relativity of inertial frames and agreement with Einstein's theory at low energies. This is accomplished by a nonlinear modification of the action of the Lorentz group on momentum space, generated by adding a dilatation to each boost in such a way that the Planck energy remains invariant. The associated algebra has unmodified structure constants. We also discuss the resulting modifications of field theory and suggest a modification of the equivalence principle which determines how the new theory is embedded in general relativity.
