                      the timelike region, accessible in the reaction
                      e+e−→¯YY, are studied. The focus is on energies close
                      to the reaction thresholds, where the properties of these
                      form factors are significantly influenced by the interaction
                      in the final ¯YY system. This interaction is taken into
                      account in the calculation, utilizing ¯YY potential models
                      that have been constructed by the Jülich group for the
                      analysis of data from the reaction ¯pp→¯YY in the past.
                      The enhancement of the effective form factor for energies
                      close to the threshold, seen in experiments of
                      e+e−→¯ΛΛ and e+e−→¯Σ0Λ, is reproduced. With
                      regard to the reactions e+e−→¯Σ−Σ+, ¯Σ0Σ0,
                      ¯Σ+Σ− a delicate interplay between the three channels
                      is observed in the results at low energies, caused by the
                      ¯ΣΣ interaction. Predictions for the electromagnetic form
                      factors GM and GE in the timelike region are presented for
                      the Λ, Σ, and Ξ hyperons.},
