, x∈C,
where f belongs to a complete metric space ℳ of
convex functions and the set C is a countable intersection of a
decreasing sequence of closed convex sets Ci in a reflexive
Banach space. Let ℱ
be the set of all f∈ℳ
for which the solutions of the minimization problem
over the set Ci converge strongly as i→∞ to the solution over the set C. In our recent work we show that
the set ℱ contains an everywhere dense Gδ subset of ℳ. In this paper, we show that the
complement ℳ\ℱ is not only of the
first Baire category but also a σ-porous set.">
