摘要
本文证明了两个涉及任意正整数 m 和正算子 P 的一对 (A,B) P 双几何或 (m,P) 双几何希尔伯特空间算子的结果。
Forms of biisometric operators and biorthogonality
The paper proves two results involving a pair (A,B) of P-biisometric or (m,P)-biisometric Hilbert-space operators for arbitrary positive integer m and positive operator P. It is shown that if A and...
