| Abstract: | We analyze how string theory dualities may be described in M-theory. T-dualities arise from scalar-vector dualities in the worldvolume of the membrane of M-theory. “Electric-magnetic” dualities arise from a duality transformation in M-theory compactified on a 3-torus, which takes the membrane into a fivebrane wrapped around the 3-torus. We show how the action of the membrane transforms into the action of the wrapped fivebrane by this fransformation. Other “electric-magnetic” dualities are related to this duality by compactifications and orbifoldings. |
