I am interested in knowing if there are any introductory textbooks on relativistic non-instantaneous action-at-a-distance interactions. The abstracts that I've read on this topic recently [1] [2] seem very interesting and I would like to learn more.

I have also read that Henri Poincaré proposed two laws of gravitational attraction compatible with the principle of relativity in July, 1905 [3] and I'm particularly interested in knowing what he was up to. I'm looking for a detailed and easy to understand mathematical explanation of his work. Any suggestions?
