Abstract
Some basic algebraic features of quasiparticle transformations are reviewed. Special nonlinear quasiparticle transformations are introduced leading to the second quantized counterparts of gerninal-type (correlated) wave functions. Algebraic representations of strong and weak orthogonality are discussed, and these issues are generalized to the case of non-orthogonal basis sets leading to the concepts of strong and weak biorthogonaltty.
