Title:  The multiplicativity problem for product maps

Abstract: 

  The multiplicativity question asks whether the maximal output p-norm
  of a product of linear maps on matrix algebras is achieved on a
  product state. For applications in quantum information theory the
  important class is the set of completely positive (CP) maps.  Recent
  work has shown that the multiplicativity property can hold in some
  cases for other classes of maps. I will give examples of non-CP maps
  for which multiplicativity holds, and then explain some implications
  for the special case where one of the maps is a qubit channel.
