The universal cover of the circle is the real line, of the torus is R2, of RP2 is the sphere S2, and of the ﬁgure-of-eight graph is the inﬁnite 4-valent tree. Since the universal cover Xe is simply connected, π 1(X,e ex0) is trivial, so its image under " - Simply connected orientable

WebbA simple closed curve in a surface is a closed loop in the surface which does not intersect itself. Equivalently it is the image of a continuous injective map from S1 into the surface. Within this project we will usually think of two simple closed curves as equivalent if they are isotopic. Fix an orientable surface Σ of genus greater than 0.

As with all projective spaces, RP is formed by taking the quotient of R ∖ {0} under the equivalence relation x ∼ λx for all real numbers λ ≠ 0. For all x in R ∖ {0} one can always find a λ such that λx has norm 1. There are precisely two such λ differing by sign. Thus RP can also be formed by identifying antipodal points of the unit n-sphere, S , in R . One can further restrict to the upper hemisphere of S and merely identify antipodal points on the … camouflage toys for kidsWebbSIMPLY-CONNECTED 3-MANIFOLDS AS BRANCHED COVERING SPACES OF S3 JOAN S.
