WebON BOTT’S VANISHING THEOREM AND APPLICATIONS TO SINGULAR FOLIATIONS S. Sertöz Published 2001 Mathematics Let M be a complex manifold with tangent bundle T which can be decomposed as T = A ⊕ B and let E be a subbundle of A. If E and B are integrable, then the graded chern ring Chern∗ (A/E) vanishes beyond the corank of E in A. WebA NOTE ON THE BOTT VANISHING THEOREM IRA MOSKOWITZ Abstract. We give a simple example of a foliated 4-ma.iifold that shows that the bound in Bott's theorem is best possible. Conventions. The following hold unless stated otherwise: (1) All manifolds are closed, oriented, and C°°. (2) All 77 * are with R-coefficients. 1. Introduction.
