Using the technique of block-operator matrices of bounded linear operators on a Hilbert space,the geometry structure of the two idempotent operators of P and Q is obtained.

利用Hilbert空间中有界线性算子的分块矩阵技巧,得到了关于P,Q两个幂等算子的几何结构之后,研究了幂等算子以及其乘积的线性组合的性质,证明了当c1(c2+c3)≠0,c2(c1+c3)≠0,c1+c2+c3≠0时,在c2c+1c3[-1,0]或者c1c+2c3[-1,0]的条件下,算子c1P+c2Q+c3PQ的值域闭性与系数组(c1,c2,c3)的选取无关。

广义幂等算子差的可逆性

A∈B(H) is said to be generalized quadratic operator if A satisfies AP=PA=A and the quadratic equation A2=αA+βP, where α, β∈C and P∈B(H) is nonzero idempotent.

如果A∈B(H)满足二次算子方程A2=αA +βP,其中α,β∈C,P是一个非零的幂等算子且AP=PA=A,则称A为广义二次算子。
