Query: Invitation to higher local fields, Part II, section 5: Harmonic analysis
  on algebraic groups over two-dimensional local fields of equal characteristic   This work introduces author's approach to harmonic analysis on algebraic
groups over functional two-dimensional local fields. For a two-dimensional
local field a Hecke algebra which is formed by operators which integrate
pro-locally-constant complex functions over a non-compact domain is defined and
its properties are described.
