Part 2: Metrics and Norms 1. Norms and convergence: (a) Prove the l2 metric defined in class is a valid norm on R2 (b) Prove that in R2, any open ball in 12 ("Euclidean metric") can be enclosed in an open ball in the loo norm ("sup" norm). (c). Say I have a collection of functions f:I R. Say I (1,2). Consider the convergence of a sequence of functions fn (z) → f(x) in 12-Show that the convergence amounts to...
With explanation! 3. Let B2 be the linear operator B2f (x):- f(0)2 2 (1f (1)2, which maps functions f defined at 0, 1 to the quadratic polynomials Pa. This is the Bernstein operator of degree 2, Let T = B21Py be the restriction of B2 to the quadratics.

Answer C 6. Let f be a continuous function on [0, oo) such that 0 f(z) Cl- for some C,e> 0, and let a = fo° f(x) da. (The estimate on f implies the convergence of this integral.) Let fk(x) = kf(ka) a. Show that lim00 fk(x) = 0 for all r > 0 and that the convergence is uniform on [8, oo) for any 6> 0. b. Show that limk00 So ()dz = a. c. Show that lim00 So...
Show that the sup-norm in C[0, 1] does not come from an inner product by showing that the parallelogram law fails for some f, g. Note that the sup-norm in C[0, 1] is ||f||∞ = {|f(x) : x ∈ [0, 1]}.
Could someone help me with part (b) and part (c)? Please make the solution clear to understand, thanks! Let H be a separable Hilbert space with basis {e,n}neN and define Pn as the orthogonal projection onto spanfe1,... ,en (a) A sequence of operators Tn e B(H) is said to converge strongly to T if ||Th-T,nh|| converges to 0 for all h E H (note that strong convergence is actually weaker than operator norm convergence-think of this as the difference between...
