Abstract
A canonical finite-temperature mean-field approximation and a higher-order approach, which includes particular two-body correlations, are developed and compared with the exact (canonical) and the usual mean-field (grand-canonical) results within the context of an exactly solvable fermion model. Special projected statistics in a particular canonical subspace are also discussed.Keywords
