It gives an equality of cohomology classes in Bott–Chern cohomology, which is a refinement for complex manifolds of de Rham cohomology. When the manifolds are K?hler, our main result is known. A proof can be given using the elliptic Hodge theory of the fibres, its deformation via Quillen‘s superconnections, and a version in families of the ‘fantastic cancellations‘ of McKean–Singer in local index theory. In the general case, this approach breaks down because the cancellations do not occur any more.?One tool used in the book is a deformation of the Hodge theory of the fibres to a hypoelliptic Hodge theory, in such a way that the relevant cohomological information is preserved, and ‘fantastic cancellations‘ do occur for the deformation. The deformed hypoelliptic Laplacian acts on the total space of the relative ?tangent bundle of the fibres. While the original hypoelliptic Laplacian discovered by the author can be described in terms of the harmonic oscillator along the tangent bundle and of the geodesic flow, here, t | | 出版日期 | Book 2013 | | 關(guān)鍵詞 | Riemann-Roch theorems and Chern characters; analytic torsion; determinants and determinant bundles; hea | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-00128-9 | | isbn_softcover | 978-3-319-03389-1 | | isbn_ebook | 978-3-319-00128-9Series ISSN 0743-1643 Series E-ISSN 2296-505X | | issn_series | 0743-1643 | | copyright | Springer Basel 2013 |
