A multiobjective optimization problem is πΆπ simplicial if the Pareto set and the Pareto front are πΆπ diffeomorphic to a simplex and, under the πΆπ diffeomorphisms, each face of the simplex corresponds to the Pareto set and the Pareto front of a subproblem, where 0 β€ π β€ β. In the paper titled βTopology of Pareto sets of strongly convex problemsβ, it has been shown that a strongly convex πΆπ problem is πΆπ β1 simplicial under a mild assumption on the ranks of the differentials of the mapping for 2 β€ π β€ β. On the other hand, in this paper, we show that a strongly convex πΆ1 problem is πΆ0 simplicial under the same assumption. Moreover, we establish a specialized transversality theorem on generic linear perturbations of a strongly convex πΆπ mapping (π β₯ 2). By the transversality theorem, we also give an application of singularity theory to a strongly convex πΆπ problem for 2 β€ π β€ β.
