Question 26197: Complete Total Mapping Qualification Precedes Membership Equivalence

Original question and givens

Use source carrier=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23], target carrier=[0, 1, 2], aligned mapping=[0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2]. Sort domain values with their associated images, not independently. A null or outside image is not a total map. Give (source_carrier, target_carrier, mapping_rows, total, first_invalid_image_or_null, certificate).

• G001 — Use source carrier=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23], target carrier=[0, 1, 2], aligned mapping=[0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2]. Sort domain values with their associated images, not independently. A null or outside image is not a total map. Give (source_carrier, target_carrier, mapping_rows, total, first_invalid_image_or_null, certificate).

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

source roles = [mreduction-total-map-qualification]

derived = [[source_carrier, target_carrier, mapping_rows, total, first_invalid_image_or_null, certificate]]

source roles = [Reduction ORIGINAL map, [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23], [0, 1, 2], [0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2]]

derived = [[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23], [0, 1, 2], [0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2], [[0, 0, Yes], [1, 1, Yes], [2, 2, Yes], [3, 0, Yes], [4, 1, Yes], [5, 2, Yes], [6, 0, Yes], [7, 1, Yes], [8, 2, Yes], [9, 0, Yes], [10, 1, Yes], [11, 2, Yes], [12, 0, Yes], [13, 1, Yes], [14, 2, Yes], [15, 0, Yes], [16, 1, Yes], [17, 2, Yes], [18, 0, Yes], [19, 1, Yes], [20, 2, Yes], [21, 0, Yes], [22, 1, Yes], [23, 2, Yes]], Yes, null]

Reverse checks

• S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
• S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23], [0, 1, 2], [[0, 0, Yes], [1, 1, Yes], [2, 2, Yes], [3, 0, Yes], [4, 1, Yes], [5, 2, Yes], [6, 0, Yes], [7, 1, Yes], [8, 2, Yes], [9, 0, Yes], [10, 1, Yes], [11, 2, Yes], [12, 0, Yes], [13, 1, Yes], [14, 2, Yes], [15, 0, Yes], [16, 1, Yes], [17, 2, Yes], [18, 0, Yes], [19, 1, Yes], [20, 2, Yes], [21, 0, Yes], [22, 1, Yes], [23, 2, Yes]], Yes, null, many_one_reduction_requires_a_complete_total_map_before_membership_audit)

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
