关于递归生成加权移位算子正的2次亚正规
On Positively Quadratically Hyponormal of Recursively Generated Weighted Shits

对于递归生成的加权移位算子Wα(x,y)∶√y,√x,(√a,√b,√c)^,利用无穷维矩阵的正定性得到了其2-亚正规性和正的2次亚正规性,推广了已有的一些结论.
The 2-hyponormality and positively quadratically hyponormality of recursively generated weighted shift Wα(x,y)with α(x,y):y,x,(a,b,c) are considered by using the positivity of in finite dimension matrix,which extend some known results
