      Dellacherie Lefebvre, Claude; Martínez Aguilera, Servet; San Martín Aristegui, Jaime (2009)
      We prove that the class of generalized ultrametric matrices (GUM) is the largest class of bipotential matrices stable under Hadamard increasing functions. We also show that any power α ≥ 1, in the sense of Hadamard ...
