As stated, one of the axioms for a linear space is redundant. Which one and why? Section 3.10 #11 - 22. Read the proofs of Theorems 3.5 and 3.7, and compare them with the proof of Theorem 1.10. Section 3.13 #5, 6, 8, 12, 14. Section 4.4 #11 - 15, 25 - 28. Let T: V -> W be a linear transformation from V into W, both linear spaces. Prove that the null space of T is a subspace of V. Let V be a Euclidean space and S a finite dimensional subspace of V with an orthonormal basis. Let T:V -> S be the linear transformation where T(f) is the projection of the element f from V onto the subspace S. Prove that N(T) = S^{perp}, the orthogonal complement of S.

Things you should know |
Basic set theory and propositional logic. Here's a
An Elementary Introduction to Logic and Set Theory.
I have also just requested that the books
Discrete Mathematics
by Johnsonbaugh and _Discrete Mathematics and Its Applications_ by Rosen
be put on reserve at the library. The first chapters will cover logic,
sets, and basic proof techniques. |
