Archimedean bundle group - Archimedean bundle group

a ( bc )= abac , ( bc ) abacaa ( bc )= abac , ( bc ) abacaThis condition is equivalent to abacbc , cacb when G is considered as an ordered set. In a lattice group G , if x >1 (identity element) and y is any element, then for any natural number n , if xny , then G is said to be an Archimedean lattice group. In the set Q of positive rational numbers, if we take two elements a and b , and reduce them to m / d and n / d , and define ab = (the greatest common divisor of m and n )/ d and ab = (the least common multiple of m and n )/ d , then ab and ab are determined regardless of the method of reducing them, and become Archimedean lattice groups. …

Japanese:

… a(bc)=abac,(bc)abaca a(bc)=abac,(bc)abacaこの条件はGを順序集合と考えたとき, ab ⇒ acbc,cacbということと同値である。 束群Gにおいて,x>1(単位元)であり,yが任意の元ならば,適当な自然数nをとれば,xnyとなるとき,Gはアルキメデス的束群であるという。 正の有理数全体Qにおいて,二元a,bをとったとき,それを通分して,m/d,n/dと表し,ab=(mnの最大公約数)/d,ab=(mnの最小公倍数)/dと定めると,ab,abは通分のしかたにはかかわらず決まり,アルキメデス的束群になる。…
