标题： On the (non) existence of several gravitomagnetic effects

摘要： 由于麦克斯韦方程和广义相对论弱场和慢运动极限下得到的引力磁方程之间的相似性，人们可以问是否可以通过引力磁发电机放大种子固有旋转或自旋运动，类似于众所周知的发电机效应。 使用引力磁方程的伽利略极限，这个问题的答案是否定的，这是由于引力磁方程的“磁”伽利略极限在物理上是不一致的。 此外，我们证明尽管有一些说法，但引力迈斯纳效应并不存在。 显示英文摘要

摘要： Due to the resemblance between Maxwell and the gravitomagnetic equations obtained in the weak field and slow motion limit of General Relativity, one can ask if it is possible to amplify a seed intrinsic rotation or spin motion by a gravitomagetic dynamo, in analogy with the well-known dynamo effect. Using the Galilean limits of the gravitomagnetic equations, the answer to this question is negative, due to the fact that a "magnetic" Galilean limit for the gravitomagnetic equations is physically inconsistent. Also, we prove that, in spite of some claims, a gravitational Meissner effect does not exists.
