The Ray-Singer analytic torsion is then deduced, generalizing thus Bost's result for ample line bundles and Ray-Singer's ones for flat bundles, of which we a geometric interpretation is given.10 pages, in frenchDifferential Geometry58A14; 58G25; 14K99; 47A75Le spectre et la torsion analytique des fibres en droites sur les tores complexestext
