Weak Field Expansion of Gravity : Graphs, Matrices and Topology
We present some approaches to the perturbative analysis of the classical and quantum gravity. First we introduce a graphical representation for a global SO(n) tensor (∂)hαβ , which generally appears in the weak field expansion around the flat space: gμν = δμν +hμν . Making use of this representation, we explain 1) Generating function of graphs (Feynman diagram approach), 2) Adjacency matrix (Ma...

متن کاملTesting Weak-Field Gravity
One of the most important problems in science today is the origin of \dark matter". Much of our understanding of the history and present state of the universe depends upon conjectures about the nature of dark matter. In some sense, our knowledge rests upon a \house of cards" which won't be buttressed until progress is made in identifying what dark matter represents. Most research today is found...
متن کاملWeak-field gravity of circular cosmic strings.
A weak-field solution of Einstein’s equations is constructed. It is generated by a circular cosmic string externally supported against collapse. The solution exhibits a conical singularity, and the corresponding deficit angle is the same as for a straight string of the same linear energy density. This confirms the deficit-angle assumption made in the Frolov-Israel-Unruh derivation of the metric...
