The G -matrices are derived on the basis of meson-theoretical hyperon-nucleon and hyperon-hyperon potentials from the Nijmegen group (model-D, model-F, soft-core model) and the Jülich group (version-A, version-B). In order to make easy applications to hypernuclei, they are parametrized to express in terms of three-range Gaussian radial functions with the density dependence being in the quadratic form of the Fermi momentum. Through the structure calculations of Λ -, Σ -, ΛΛ - and Ξ -hypernuclei, properties of these G -matrix interactions have been investigated in the ΛN , ΣN , ΛΛ and ΞN channels, respectively.
