WebWe propose an efficient numerical method for solving a non-linear ordinary differential equation describing the stellar structure of the slowly rotating polytropic fluid sphere. The Ramanujan’s method i.e. an iterative method has been used to ... a non-linear ordinary differential equation describing the stellar structure of the slowly ... WebYou remove one point (say, $\theta=0$) from one coordinate chart, and you remove the other ($\theta=\pi$) from the second coordinate chart. Now you have two charts which are everywhere invertible and every point ${(\theta,\phi)}$ of the sphere is included in at least one of them. $\endgroup$ –

Webresulting space is a manifold (in fact, a sphere). One can ask the following strengthened version of Question 2: Question 3. Does every topological manifold admit a combinatorial triangulation (or, equivalently, a piecewise linear structure)? Answering the three questions above has inspired much research in topology.
