Abstract
The algebraic structure of Thermo Field Dynamics lies in the -deformation of the algebra of creation and annihilation operators. Doubling of the degrees of freedom, tilde-conjugation rules, and Bogoliubov transformation for bosons and fermions are recognized as algebraic properties of and of , respectively.
