Web2. (a) Define uniform continuity on R for a function f: R → R. (b) Suppose that f,g: R → R are uniformly continuous on R. (i) Prove that f + g is uniformly continuous on R. (ii) Give an example to show that fg need not be uniformly continuous on R. Solution. • (a) A function f: R → R is uniformly continuous if for every ϵ > 0 there exists δ > 0 such that f(x)−f(y) < ϵ for … Weba ≥ inf A, b ≥ inf B, and hence a +b ≥ inf A+inf B. Therefore x := inf A+inf B is a lower bound of S. To prove that x is the greatest lower bound, let us show that for any ǫ > 0 we can find s ∈ S such that x ≤ s < ǫ (which would guarantee that no lower bound of S greater than x exists). For this, find a ∈ A

Webfor every x ∈ X, then the sum f + g is defined to be the function that maps x ∈ X to f(x) + g(x) ∈ IR. The difference f − g is defined to be f + (−g). It is well defined if {f(x),−g(x)} 6= … WebShow that sup and inf are measurable if { } is a sequence of measurable functions. Let { } be a sequence of measurable functions E -> . Show that the functions sup and inf are …
WebThe first interval in the partition is I1= [0,x1], where 0 < x1≤ 1, and M1= 1, m1= 0, since f(0) = 1 and f(x) = 0 for 0 < x ≤ x1. It follows that U(f;P) = x1, L(f;P) = 0. Thus, L(f) = 0 and U(f) = … Web键盘快捷键功能 Dell 中国
WebSo you can't use inf unless you first define (or import from somewhere) a variable with that name. -inf is just the string you get when converting negative infinity to a string. It's not a valid floating point literal by itself. What value should I give instead of … WebProof: For r ∈ IR, let A = {x ∈ E : f(x) > r} and A = {x ∈ E : g(x) > r}. Then A is measurable and A − B,B − A are subsets of {x ∈ E : f(x) 6= g(x)} so that they have zero measures. Since B = (B −A) [(B \ A) = (B −A) [(A−(A−B)) is measurable. Thus, g is measurable. 2 Operations on measurable functions
