β¦ Synopsis
We emphasise the geometrical partnership of the vie rbein and the spin 3 field in the structure of the supergravity Lagrangian. Both fields are introduced as components of the same matrix differential form. The only local symmetry of the theory is SL(2, 63. Recently we have expressed [1] the supergravity Lagrangian [2] in Cartan's geometrical language

The derivation of absolute (moduli-independent) U-invariants for all N > 2 extended supergravities at D = 4 in terms of (moduli-dependent) central and matter charges is reported. These invariants give a general denition of the \topological" Bekenstein{Hawking entropy formula for extremal black-holes
