I read some text to find it's definition
Is it possible to tell me it's definition?
I read below statements about local and global geometry and I didn't understand it. is it possible tell me it.
"If M ( a manifold) has a trivial topology, a single neighborhood can be extended globally, and geometry is indeed trivial; but if M contains non-contractible curves, such as extension may not be possible."
