摘要:

在这项工作中,我们解决的可实现性的李雅普诺夫图标记GS奇点,即定期,锥,惠特尼,双交叉和三重交叉奇点,连续流上的奇异封闭$2$ -流形$\mathbf{M}$。此外,欧拉示性数的计算与$\mathbf{M}$上的流的GS奇异性的类型。局部地,一个完整的分类定理的GS奇点的最小隔离块的分支的一个流形,使边界。

英文摘要:

In this work we address the realizability of a Lyapunov graph labeled with GS singularities, namely regular, cone, Whitney, double crossing and triple crossing singularities, as continuous flow on a singular closed $2$-manifold $\mathbf{M}$. Furthermore, the Euler characteristic is computed with respect to the types of GS singularities of the flow on $\mathbf{M}$. Locally, a complete classification theorem for minimal isolating blocks of GS singularities is presented in terms of the branched one manifolds that make up the boundary.
