The Magnus series is the formal expansion for the logarithm of the S-matrix, similar to the Dyson series being the formal expansion for the S-matrix itself. Magnus amplitudes refer to the matrix elements of the log of the S-matrix. As is well known, string theory has its roots in the bootstrap programme. What can we learn by bootstrapping Magnus amplitudes? I will report on some preliminary explorations in this direction.
