1. Why do S1 and S2 exist? 2. Where does equation 2 come from? subsets of a vector space and let S, be a subset of S2. Then Let Si and S2 be finite subsets of a vector the following statements are true: (a) If S, is linearly dependent, so is S2. (b) If S2 is linearly independent, so is Si. Proof Let Si = {V1, V2, ..., vk and S2 = {V1, V2, ..., Vk, Vx+1, ..., Vm). We...
5. Let ф: S1 S2 be a diffeomorphism. a. Show that S is orientable if and only if S2 is orientable (thus, orientability is preserved by diffeomorphisms). b. Let S, and S2 be orientable and oriented. Prove that the diffeomorphism ф induces an orientation in S. Use the antipodal map of the sphere (Exercise 1, Sec. 2-3) to show that this orientation may be distinct (cf. Exercise 4) from the initial one (thus, orientation itself may not be preserved by...

Consider the following four problems: Bin Packing: Given n items with positive integer sizes s1,s2,...,sn, a capacity C for bins and a positive integer k, is it possible to pack the n items using at most k bins? Partition: Given a set S of n integers, is it possible to partition S into two subsets S1 and S2 so that the sum of the integers in S1 is equal to the sum of the integers in S2? Longest Path: Given...
