Pontryagin Numbers and Nonnegative Curvature
We prove that any rational linear combination of Pontryagin numbers that is not a multiple of the signature is unbounded on connected closed oriented manifolds of nonnegative sectional curvature. Combining our result with Gromov’s finiteness result for the signature yields a new characterization of the L-genus.
متن کاملInfinitesimal Isometries along Curves and Generalized Jacobi Equations
On a Riemannian manifold, a solution of the Killing equation is an infinitesimal isometry. Since the Killing equation is overdetermined, infinitesimal isometries do not exist in general. The complete prolongation of the Killing equation is a PDE on the bundle of 1-jets of vector fields. Restricted to a curve, it becomes an ODE that generalizes the Jacobi equation. A solution of this ODE is call...
متن کاملOn the infinitesimal isometries of manifolds with Killing spinors
We study the Lie algebra of infinitesimal isometries of 7–dimensional simply connected manifolds with Killing spinors. We obtain some splitting theorems for the action of this algebra on the space of Killing spinors, and as a corollary we prove that there are no infinitesimal isometry of constant length on a 7–dimensional 3– Sasakian manifold (not isometric to a space form) except the linear co...
متن کاملPlane Isometries and the Complex Numbers
The length of a vector v = ( x y ) in R2 is || ( x y ) || = √ x2 + y2, and the distance between two vectors v and w is the length of their difference: ||v − w||. A function h : R2 → R2 is called an isometry when it preserves distances: ||h(v)− h(w)|| = ||v −w|| for all v and w in R2. Examples of isometries include translation by ( 1 −1/2 ) , a rotation by 40 degrees counterclockwise around the ...
متن کاملMeasuring Fractals by Infinite and Infinitesimal Numbers
Traditional mathematical tools used for analysis of fractals allow one to distinguish results of self-similarity processes after a finite number of iterations. For example, the result of procedure of construction of Cantor’s set after two steps is different from that obtained after three steps. However, we are not able to make such a distinction at infinity. It is shown in this paper that infin...
