Abstract: Aを有限の大局次元を持つサイクル型の単列環で、その単純加群の個数をnとする。k<n/2なる任意の自然数kに対して環の長さlがn/k以上の最小の整数であるとき、Aの大局次元は2n-2k-1以下である。
Let A be the finite dimensional serial algebra of cyclic type over an algebraically closed field which has finite global dimension, and let n be the number of the non isomorphic simple left modules of A. Let k be a positive integer with k<n/2. If the length of A is the minimal positive integer which greater than n/k, then the global dimension of A is less than or equal to 2n-2k-1.
