The Dirac's Torsion

Authors: Antoine Balan
Comments: 1 page, written in french

We propose here to define a torsion called Dirac's torsion because of the construction.

A Remark on the Localization Formulas About Two Killing Vector Fields

Authors: Xu Chen
Comments: 13 Pages.

In this article, we will discuss a localization formulas of equlvariant cohomology about two Killing vector fields on the set of zero points ${\rm{Zero}}(X_{M}-\sqrt{-1}Y_{M})=\{x\in M \mid |Y_{M}(x)|=|X_{M}(x)|=0 \}.$ As application, we use it to get formulas about characteristic numbers and to get a Duistermaat-Heckman type formula on symplectic manifold.

A Poincaré-Hopf Type Formula for A Pair of Vector Fields

Authors: Xu Chen
Comments: 7 Pages.

We extend the reslut about Poincar\'e-Hopf type formula for the difference of the Chern character numbers (cf.[3]) to the non-isolated singularities, and establish a Poincar\'e-Hopf type formula for a pair of vector field with the function $h^{T_{\mathbb{C}}M}(\cdot,\cdot)$ has non-isolated zero points over a closed, oriented smooth manifold of dimension $2n$.

The 5th Euclidean postulate is 2300 years old mathematical impossibility. I have worked on this problem for nearly b35 years and found a number of consistent solutions. My findings have been appeared in international peer reviewed research journals. Generation of power freely from space, space Bombs, Lion’s Tonic and Lemurian Yoga are my ambitious scientific projects. Interested researchers and people may contact me at +91 8508991577.

Poliedros Fórmulas Indemostradas

Authors: Carlos Alejandro Chiappini
Comments: 7 Pages.

Leonhard Euler demostró que en un poliedro regular convexo hay tres números ue cumplen una ley, expresada en una ecuación conocida como fórmula de Euler. Son el número de caras, el número de vértices y el número de aristas. Este documento presenta algunas fórmulas más, obtenidas por ensayo y error a partir de una tabla que contiene los datos de los 5 poliedros regulares convexos. Estas fórmulas indemostradas tienen rasgos verosímiles. Buscar el modo de demostrar la invalidez o la validez de esas fórmulas podría ser, para las personas amantes de la topología, una tarea interesante.
