线性丢番图方程解的界
Bounds for solution of linear diophantine equations
摘要:
给定线性丢番图方程Ax=b,秩A=m.设d是矩阵(A)的m × m个子式的绝对值的最大值|(b)。证明了若M={x:Ax=b,x非负且为整数}非空,则存在x=(x1,...,xn),使得xi不超过d(i= 1,2,..,n)。
英文摘要:
Given linear diophantine equation Ax=b, rank A=m. Let d be the maximum of absolute values of the mxm minors of the matrix (A | b). It is shown that if M={x : Ax=b, x nonnegative and integer} is nonempty, then there exists x=(x1,...,xn) in M, such that xi does not exceed d (i=1,2,..,n).
