第 27017 題：一致極限保持連續

原題與已知條件

共同domain、逐項continuity與同一N控制全部x的uniform責任。操作=uniform-continuity-transfer；資料={"n":17,"lipschitz":2,"error_bound":[1,20],"epsilon":1}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

• G001 — 共同domain、逐項continuity與同一N控制全部x的uniform責任。操作=uniform-continuity-transfer；資料={"n":17,"lipschitz":2,"error_bound":[1,20],"epsilon":1}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。

逐步推導

source roles = [uniform-continuity-transfer]

derived = [[N, Lipschitz_constant, uniform_error_bound, epsilon, delta, triangle_bound, strict_triangle_bound, certificate]]

Uniform ORIGINAL three times uniform error := mul(3, 1/20)

Uniform ORIGINAL three times uniform error = 3/20

Uniform ORIGINAL three times Lipschitz constant := mul(3, 2)

Uniform ORIGINAL three times Lipschitz constant = 6

Uniform ORIGINAL epsilon over threeL := div(1, 6)

Uniform ORIGINAL epsilon over threeL = 1/6

Uniform ORIGINAL twice uniform error := mul(2, 1/20)

Uniform ORIGINAL twice uniform error = 1/10

Uniform ORIGINAL epsilon over three := div(1, 3)

Uniform ORIGINAL epsilon over three = 1/3

Uniform ORIGINAL three term triangle upper bound := sum(1/10, 1/3)

Uniform ORIGINAL three term triangle upper bound = 13/30

source roles = [17, 2, 1/20, 1]

derived = [ASSUME f_N is L-Lipschitz on the WHOLE domain, ASSUME EVERY x:abs(f_N(x)-f(x))<=error_bound, 1/6]

source roles = [17, 2, 1/20, 1, 1/6]

derived = [abs(f(x)-f(y))<=abs(f(x)-f_N(x))+abs(f_N(x)-f_N(y))+abs(f_N(y)-f(y)), abs(x-y)<1/6 => bound<13/30, 是]
