Query: Invitation to higher local fields, Part I, section 6: Topological Milnor
  K-groups of higher local fields   Certain topologies on Milnor K-groups of higher local fields K are studied.
These are related to the topology on the multiplicative group and important for
explicit higher local class field theory. The structure of the quotient of
Milnor K-groups modulo the intersection of all neighbourhoods of zero is
described.
