Abstract:
Tensor calculation of suffix-contraction is carried out by a C-program. Tensors are represented graphically, and the algorithm makes use of the topology of graphs. Classical and quantum gravity, in the weak-field perturbative approach, is a special interest. Examples of the leading order calculation of some general invariants such as R_{\mn\ls}R^{\mn\ls} are given. Application to Weyl anomaly calculation is commented.- Feynman graph: higher-order
- algebra: tensor
- programming
