One main tool used is the equivalence of categories established by Block between the derived category of bounded complexes with coherent cohomology and the homotopy category of antiholomorphic superconnections. Chern-Weil theoretic techniques are then used to construct forms that represent the Chern character. The main theorem is then established using methods of analysis, by combining local index theory with the hypoelliptic Laplacian. Coherent Sheaves, Superconnections, and Riemann-Roch-Grothendieck is an important contribution to both the geometric and analytic study of complex manifolds and, as such, it will be a valuable resource for manyresearchers in geometry, analysis, and mathematical physics. .Progress in Mathematics,2296-505X ;347Algebra, HomologicalK-theoryDifferential equationsGeometry, DifferentialCategory Theory, Homological AlgebraK-TheoryDifferential EquationsDifferential GeometryAlgebra, Homological.K-theory.Differential equations.Geometry, Differential.Category Theory, Homological Algebra.K-Theory.Differential Equations.Differential Geometry.516.183Bismut Jean-Michel44924Shen Shu1439118Wei Zhaoting1439119MiAaPQMiAaPQMiAaPQBOOK9910763598003321Coherent Sheaves, Superconnections, and Riemann-Roch-Grothendieck3601319UNINA
