Under the ∑-C0-BD equivalence on bifurcation problems,the ∑-C0-BD finite determination of bifurcation problems from the weighted point view is being discussed.Some criteria on the ∑-C0-BD finite determination of bifurcation problems is then obtained in terms of an analytic-geometric nondegeneracy condition,which generalize the result on the C0 finite determination of bifurcation problems.
