| Sumario: | Duality rotations in nonlinear electromagnetism are presented and basic examples reviewed. We then describe the nontrivi al example of Born-Infeld theory with n abelian gauge fields and with Sp (2 n, R ) self-duality. The central role of duality symmetry in four dimensional extended supergravity theories is explained and ex- plicitly illustrated in two examples ( N =4and N = 8 supergravities). Duality rotations in N = 2 supergravities are also discussed |
