WebIn mathematics, and especially differential geometry, the Quillen metric is a metric on the determinant line bundle of a family of operators. It was introduced by Daniel Quillen for certain elliptic operators over a Riemann surface, and generalized to higher-dimensional manifolds by Jean-Michel Bismut and Dan Freed.. The Quillen metric was used by … WebDeterminant line bundles entered differential geometry in a remarkable paper of Quillen [Q]. He attached a holomorphic line bundle L to a particular family of Cauchy-Riemann operators over a Riemann surface, constructed a Hermitian metric on L, and calculated its curvature. At about the same time Atiyah and

Visit Stack Exchange Web0. Introduction. We shall now show how the hyperbolic metric of a compact Riemann surface of genus g, g 2 2 leads to the existence of a positive line bundle on the moduli space jMtg of stable curves (noded Riemann surfaces). Weil introduced a Kahler metric for the Teichmuller space, based on the Petersson product for automorphic forms: (so, ,> = bari bergamo ryanair
