A Poincaré-Hopf type formula for Chern character numbers
For two complex vector bundles admitting a homomorphism with isolated singularities between them, we establish a Poincaré-Hopf type formula for the difference of the Chern character numbers of these two vector bundles. As a consequence, we extend the original Poincaré-Hopf index formula to the case of complex vector fields.
متن کاملThe generalized Chern character and Lefschetz numbers in W * - modules
We define N-theory being some analogue of K-theory on the category of von Neumann algebras such that K 0 (A) ⊂ N 0 (A) for any von Neumann algebra A. Moreover, it turns out to be possible to construct the extension of the Chern character to some homomorphism from N 0 (A) to even Banach cyclic homology of A. Also, we define generalized Lefschetz numbers for an arbitrary unitary endomorphism U of...
متن کاملChern Numbers and Oriented Homotopy Type
1. Statement of results. This note announces the solution of the following problem, a more precise version of which appears in §2: (1) Determine the linear combinations of rational Chern numbers (of almost-complex manifolds) that are invariants of oriented homotopy type (of almost-complex manifolds). Milnor, who posed the problem, conjectured that every such homotopy invariant could be expresse...
متن کاملChern numbers of Chern submanifolds
We present a solution of the generalized Hirzebruch problem on the relations between the Chern numbers of a stably almost complex manifold and the Chern numbers of its virtual Chern submanifolds.

نامساوی کوشی-شوارتز در حالت کلاسیک در فضای اندازه فازی برقرار نمی باشد اما با اعمال شرط هایی در مسئله مانند یکنوا بودن توابع و قرار گرفتن در بازه صفر ویک می توان دو نوع نامساوی کوشی-شوارتز را در فضای اندازه فازی اثبات نمود.
