Abstract	Reexamining BCS theory leads one to formulate a generalized BEC formalism (GBEC) that is essentially a boson–fermion (BF) model with not two but three constituents, two bosonic being two-electron Cooper pairs (2eCPs) plus two-hole CPs (2hCPs), along with unpaired electrons. This ternary BF model contains three new ingredients: (i) CPs as real bosons in contrast to BCS pairs, which are at best so-called “hard-core bosons,” (ii) 2hCPs explicitly accounted for on an equal footing with 2eCPs, and (iii) four BF vertex interactions (analogous to electron-phonon vertices) describing the formation and dissociation of both 2eCPs and 2hCPs. The two pure gauge-invariant GBEC phases (of a total of four including the trivial normal phase) that result exhibit substantially higher T $_{ c }$s than BCS theory. In addition, in contrast to the well-known BCS exponential rise of T $_{ c }$ from zero, the GBEC scheme exhibits the linear rise as function of doping typically observed in high-T $_{ c }$ superconductors.
