Invariance under conformal coordinate and point transformations
✍ J. Beckers; S. Sinzinkayo 📂 Article 📅 1984 🏛 Elsevier Science 🌐 English ⚖ 486 KB

Coordinate and point transformations are studied in the context of conformal symmetry. When invariance requirements on arbitrary rank tensors are involved in both contexts, the similitudes and differences in transformation laws and invariance conditions are analysed in connection with those on tenso

A variational principle for Lagrangian densities containing derivatives of real order is formulated and the invariance of this principle is studied in two characteristic cases. Necessary and sufficient conditions for an infinitesimal transformation group (basic Nöther's identity) are obtained. These
