The BCS superconducting instability of a Fermi system (due to an attractive interparticle interaction) and the BoseEinstein condensation of bosons below a critical temperature can be bridged by following the continuous evolution between the two (BCS and BoseEinstein) limits as the strength of the attractive fermion interaction is increased. In addition to being of specific interest for hightemperature (cuprate) superconductors, a theoretical study of this evolution leads to a deeper understanding of the phenomenon of superconductivity per se. This paper provides a survey of the main ideas and results obtained in this field, with emphasis on the perspectives for future research.

Keywords: superconductivity, theory and models of the superconducting state, BCS theory and its developments, BoseEinstein condensation
