第 22114 題：有限因數格上的Möbius反演

原題與已知條件

positive integer domain、完整positive divisor set與完整UPF-derived Mobius values。操作=mobinv-forward-divisor-transform；資料={"n":14,"a":4,"b":1}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

• G001 — positive integer domain、完整positive divisor set與完整UPF-derived Mobius values。操作=mobinv-forward-divisor-transform；資料={"n":14,"a":4,"b":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 operation=mobinv-forward-divisor-transform;original snapshot and mathematics retained

explicit ordered source output fields=[n, divisor_value_rows, F_n, certificate]

Mobius inversion ORIGINAL forward:actual positive input=14;check complete integer range1..14

ALL positive divisors INCREASING=[1, 2, 7, 14];not only primes/proper divisors or all integers<=n

Mobius inversion ORIGINAL forward f(1) ORIGINAL a times divisor := mul(4, 1)

Mobius inversion ORIGINAL forward f(1) ORIGINAL a times divisor = 4

Mobius inversion ORIGINAL forward f(1) plus ORIGINAL b := sum(4, 1)

Mobius inversion ORIGINAL forward f(1) plus ORIGINAL b = 5

Mobius inversion ORIGINAL forward f(2) ORIGINAL a times divisor := mul(4, 2)

Mobius inversion ORIGINAL forward f(2) ORIGINAL a times divisor = 8

Mobius inversion ORIGINAL forward f(2) plus ORIGINAL b := sum(8, 1)

Mobius inversion ORIGINAL forward f(2) plus ORIGINAL b = 9

Mobius inversion ORIGINAL forward f(7) ORIGINAL a times divisor := mul(4, 7)

Mobius inversion ORIGINAL forward f(7) ORIGINAL a times divisor = 28

Mobius inversion ORIGINAL forward f(7) plus ORIGINAL b := sum(28, 1)

Mobius inversion ORIGINAL forward f(7) plus ORIGINAL b = 29

Mobius inversion ORIGINAL forward f(14) ORIGINAL a times divisor := mul(4, 14)

Mobius inversion ORIGINAL forward f(14) ORIGINAL a times divisor = 56

Mobius inversion ORIGINAL forward f(14) plus ORIGINAL b := sum(56, 1)

Mobius inversion ORIGINAL forward f(14) plus ORIGINAL b = 57

Mobius inversion ORIGINAL forward full forward divisor sum := sum(5, 9, 29, 57)

Mobius inversion ORIGINAL forward full forward divisor sum = 100
