對(duì)無(wú)窮乘積的斂散性進(jìn)行了研究.給出了無(wú)窮乘積與相應(yīng)的無(wú)窮級(jí)數(shù)之間斂散性的關(guān)系,并以此得到了無(wú)窮乘積斂散性的判別法.
無(wú)窮乘積;無(wú)窮級(jí)數(shù);收斂
對(duì)無(wú)窮乘積的研究一直都是分析學(xué)中的重要內(nèi)容[1-4],文獻(xiàn)[5-10]對(duì)無(wú)窮乘積斂散性的判別進(jìn)行了研究.本文探索無(wú)窮乘積與對(duì)應(yīng)的無(wú)窮級(jí)數(shù)之間斂散性的關(guān)系,得到了無(wú)窮乘積斂散性的判別法.
