New counterexamples disprove Rockafellar's sum conjecture under interior-domain condition
A newly posted paper builds explicit counterexamples to Rockafellar's sum conjecture, showing pairs of maximally monotone operators that meet the interior-domain qualification yet whose sum fails maximal monotonicity. One example is constructed on the Banach space c0 and another on l1. The results settle a long-standing open question in convex analysis and optimization theory.
