Isomorphisms of lattices of subalgebras of semirings of continuous nonnegative functions

  • E. M. Vechtomov
  • V. V. Sidorov


In this work, lattice isomorphisms of semirings C +(X) of continuous nonnegative functions over an arbitrary topological space X are characterized. It is proved that any isomorphism of lattices of all subalgebras with a unit of semirings C +(X) and C +(Y) is induced by a unique isomorphism of semirings. The same result is also correct for lattices of all subalgebras excepting the case of two-point Tychonovization of spaces.
