If you're up for Spivak's five-volume magnum opus, go for it! Apr4 answered Differential Geometry without General Topology Mar18 revised Conformally immersed Riemann surfaces and foliations added long comment Mar15 comment Conformally immersed Riemann surfaces and foliations What exactly do you mean by pushing $\Sigma$ along the frame? Mar13 answered Conformally immersed Riemann surfaces and foliations Mar6 revised Help understanding manifolds and topological spaces added image Mar6 answered Help understanding manifolds and topological spaces Mar6 comment Collecting definitions of continuity. Perhaps my community wiki comment was therefore out of line. Mar6 comment Collecting definitions of continuity. meta.math.stackexchange.com/questions/941/… Mar6 comment Collecting definitions of continuity. Should this be community wiki & big list? Mar6 comment Question about partition of open sets in $\mathbb{R^n}$ No connected open set is the disjoint union of two or more nonempty open sets. So not all of your limited rectangles can be open. Mar6 revised A continuous map that fixes the boundary of a domain pointwise is surjective pointed out error as per G. Smith Mar6 comment A continuous map that fixes the boundary of a domain pointwise is surjective -blush- Well, I suppose I ought to leave this nonanswer up as a warning to those attempting a solution without using more heavy machinery. It's so tempting. Mar2 comment Picture of a 4D knot LOL! No, literally, I mean it.
