... We spend a great deal of time in AB Calculus discussing straight line or rectilinear motion (“an object travels along the x-axis and has a position of s(t ) t 2 4t 5 , etc..”). We can now discuss motion along curved paths. As an object moves along a curve in the plane, the coordinates x and y ...

(Indeed, the same conclusion holds if π itself is merely a factor). The most important result here is the Factorization Lemma: If G is a Type I group and if π is an irredu ...

... spaces over a field F. Let T : V → W be linear. If V is finite-dimensional, then nullity(T ) + rank(T ) = dim(V ). Proof. Since V is finite dimensional, and N (T ) ⊆ V is a subspace, N (T ) is finite dimensional by Theorem 1.2. In particular, a basis {v1 , . . . , vk } for N (T ) exists, by the defi ...

... (b) A is nonsingular. (c) For each b ∈ Rn , the system Ax = b has a unique solution. Solution: Our strategy is to show that (a) implies (b), that (b) implies (c), and that (c) implies (a). Once this chain of implications is established, we can prove that any one statements implies the other two. For ...

Bounded Linear Operators on a Hilbert Space
... with its dual space H∗ . The norm of ϕy is equal to the norm of y (see Exercise 8.7), so J is an isometry. In the case of complex Hilbert spaces, J is antilinear, rather than linear, because ϕλy = λϕy . Thus, Hilbert spaces are self-dual, meaning that H and H∗ are isomorphic as Banach spaces, and an ...

A shorter proof of a theorem on hereditarily orderable spaces
... Proof: Herrlich’s theorem is that (i) ⇒ (ii), and (ii) and (iii) are equivalent in light of Lemma 3.1. Because X is metrizable, for any subspace Y ⊆ X we have Ind(Y ) ≤ Ind(X) so that Herrlich’s theorem shows that (ii) ⇒ (iv). Finally, (iv) ⇒ (iii) because if X contains a connected subset C with at ...
