Manifolds Manifolds and Manifolds


how to define manifolds and how to say what is manifold……. ha!

today in one of the books I read this line by Elie Cartan,

“The general notion of manifold is quite difficult to define with precision”

that says all !

Have a look at “A panoramic view of Riemannian geometry” By Marcel Berger
