Let d be the usual Euclidean metric on R^n and f:R^n -> R^n be any function satisfying d(f(x),f(y))
4. a) Show that the projective space with a disk removed (more precisely, the image of a disk on S2 under the natural projection pi : S2 -> P2 removed) is a M¨obius band. b) Let M be the connected sum of two copies of the projective space formed by removing a disk from each copy of P2 and gluing the resulting surfaces together ...continues
3-Dimensional Topological Group
6. Let M = SL(2) be the set of 2 × 2 matrices with unit determinant. Show that, when regarded as a subset of R4 under ( a b ) ( c d ) <--> (a, b, c, d) Exists R4 and equipped with subspace topology, SL(2) becomes a 3-dimensional topological group. That is, show that (i) SL(2) is a group under matrix multiplication, (ii) SL( ...continues
Open Sets, Connectivity and Continuous Functions
3. a) Let M be a connected topological space and let f : M ---> R be continuous. Pick m1,m2 2 M and suppose that f(m1) < f(m2). Let x 2 R be such that f(m1) < x < f(m2). Show that there is m M with f(m) = x. (Hint: Use a connectedness argument.) b) Give R1 the usual product topology as the product of infinite copies of the rea ...continues
