Abstract: The unfolding of equivariant bifurcation problems with parameter symmetry under a subgroup of left-right equivalence group is discussed.Necessary and sufficient conditions for an unfolding of such a bifurcation problem to be trivial and to be versal are given respectively.

Key words: equivariant bifurcation problem, left-right equivalence group, versal unfolding
