具有GRT 1- PN极限的空间VSL重力模型
A spatially-VSL gravity model with 1-PN limit of GRT
摘要：
标量引力模型是根据Poincare（Einstein 1921，Poincare 1905，Reichenbach 1957，Gruenbaum 1973）提出的“几何约定主义”方法建立的。原则上，这种方法允许广义相对论理论（GRT）的替代解释和公式化，具有不同的i）物理一致性标准，ii）根据哈密顿-拉格朗日力学的引力动力学，同时iii）保留与GRT的经验不相容性。在这个标量模型中，同余标准被表示为引力修正的洛伦兹变换（Broekaert 2002）。第一种类型的这些转换与引力“影响”（自然几何）和“不受影响”（坐标几何）的观察者观察到的量有关，并明确揭示了空间可变的光速（VSL）。第二种类型将未受影响的视角分流，并将受影响的观察者联系起来，恢复i）局部观察到的光速的不变性，以及ii）局部闵可夫斯基度量（Broekaert 2003）。在静态引力场的情况下，该模型恢复了史瓦西度规所隐含的现象学。适当的源运动学的情况下，现在通过引入一个“扫描速度”场w来描述：该模型然后提供了一个完全符合GRT的第一后牛顿近似的粒子和光子的哈密顿描述（Weinberg 1972，Will 1993）。
英文摘要：
A scalar gravity model is developed according the 'geometric conventionalist' approach introduced by Poincare (Einstein 1921, Poincare 1905, Reichenbach 1957, Gruenbaum1973). In principle this approach allows an alternative interpretation and formulation of General Relativity Theory (GRT), with distinct i) physical congruence standard, and ii) gravitation dynamics according Hamilton-Lagrange mechanics, while iii) retaining empirical indistinguishability with GRT. In this scalar model the congruence standards have been expressed as gravitationally modified Lorentz Transformations (Broekaert 2002). The first type of these transformations relate quantities observed by gravitationally 'affected' (natural geometry) and 'unaffected' (coordinate geometry) observers and explicitly reveal a spatially variable speed of light (VSL). The second type shunts the unaffected perspective and relates affected observers, recovering i) the invariance of the locally observed velocity of light, and ii) the local Minkowski metric (Broekaert 2003). In the case of a static gravitation field the model retrieves the phenomenology implied by the Schwarzschild metric. The case with proper source kinematics is now described by introduction of a 'sweep velocity' field w: The model then provides a hamiltonian description for particles and photons in full accordance with the first Post-Newtonian approximation of GRT (Weinberg 1972, Will 1993).
