問題2.28の解き方が分かりません。解く手順を教えて頂きたいです。

0 (2) (1) ¹ sgn(o) sgn(¹) = sgn(e) : よって sgn (7) = ±1 のとき sgn (™)=±1 (複号同順). 例 2.20. 置換o= 1 2 3 4 5 67 8 9 を互換の積に分解し, 偶置換か奇置換かを判定せよ。 7 6 8 21 4 93 5 (解答例). まず巡回置換の積に分解する。 1→7→9→5→1,26→4 → 2,3→8→3なので、 a = (38) (264) (1795) さらに互換に分解し, =(38) (24) (26) (15) (19) (17) よって sgn (r)=(-1)=1.つまり偶置換. 問題 2.27. 次の置換を互換の積に分解せよ。 また各々の置換の符号を求めよ。 (1) (1364) 1 2 3 4 5 6 7 (2) (1 2 5 3 4) (3) (2 4 6) (4) (5) 2 3 4 5 6 7 8 9 3 4 3 7 412 5 1 986572) n 文字の置換全体 (の集合) を Sm とかく. n 文字の置換 = (k 0= 1 2 www n k₁ k₂ は k1,..., km を決めれ ば一意的に定まるので, S, の元の個数はn個の順列の個数に等しく, n! である. 例えば3の場合, S3 = {e, (12), (13), (23) (123), (132) } の6(=3!) 個ある。 問題 2.28. ら の元をすべて求め, 偶置換と奇置換に分けよ.. 2.7 行列式 (テキスト 814) n個の置換を考える。 n次正方行列 A = (at) に対し、 第1行, 第2行,･･･ 第n 行の成分をそれぞれ異 なる列から1つずつとり、それらの積 41個(1) 2個 (2) ･One(n) をつくる、これに置換の符号sgn (o) をかけて和 But al 14 dot & toxx tt

3. (16 marks) Given a prime number k, we define Q(√k) = {a+b√k : a,b ≤ Q} ≤ R. This set becomes a field when equipped with the usual addition and multiplication operations inherited from R. (a) For each non-zero x = Q(√2) of the form x = a - a a+b√2, prove that x-1 b = ²-26² a²26² √2. -262 (b) Show that √2 Q(√3). You can use, without proof, the fact that √√2,√√3, are all irrational numbers. (c) Show that there cannot be a function : Q(√2)→ > Q(√3) so that : (Q(√2) - {0}, ×) → (Q(√3) − {0}, ×) and 6 : (Q(√2), +) → (Q(√3), +) are both group isomorphisms. Hint: What can you say about (√2 × √2)?
