Errors in the printed version of Calabi, E., Olver, P.J., Tannenbaum, A. Affine geometry, curve flows, and invariant numerical approximations Adv. in Math. 124 (1996) 154-196 On p. 191, eqn. (11.1) should not have a \kappa in it: $$ x_t = n, (11.1) $$ This equation should really be called the ``affine normal flow'' and the text should be modified accordingly in several places. At the very end of p. 191, there should be no exponent $2$: $ x_r\wedge n_e = |x_r| $ On p. 192, eqn. (11.8) is not quite correct. It should read: $$ b w_{rr} = w_r ^3 - (c w_r - b)^3 (11.8) $$ I would like to thank Peter Giblin for pointing out these errors.
