看來最不象酉運算元的壓縮運算元是0。The least unitary looking contraction operator is 0
看來最不象酉運算元的壓縮運算元是0 。Russell ( [ 17 ] ) has showed that, a compact perturbation, generated from unitary operator groups in infinite - dimensional linear hilbert spaces, is unable to make the perturbed semigroup exponentially stable
Russell ( [ 17 ] )曾指出,無限維hilbert空間中的酉運算元群對生成的緊擾動不能使被擾動半群具有指數穩定性。The closure of the unitary orbit of thestrongly irreducible operators in continuous nest algebra
連續套代數中強不可約運算元的酉軌道閉包Recently d. r. larson, deguang han and xingde dai have put forward some definitions such as unitary system, frame vector in terms of applying operator theory to the study of frame theory, which made the research develope rapidly
Larson , deguanghan和xingdedai把運算元代數理論運用到框架理論的研究,提出酉系統,框架向量等概念,使得框架理論的研究更上一個層次。In the third section we firstly introduce the concept of frame vector for a unitary system, then give a if - and - only - if condition for it and at last we get the condition for the sum a 1 + b 2 to be a frame vector, where a, b are two operators and 1, 2 are two frame vectors
第三節先引入酉系統的框架向量的概念,然後給出一個酉系統中框架向量的充要條件,最後得出兩個框架向量_ 1與_ 2 ,分別經過兩個運算元a , b作用后,它們的和a _ 1 + b _ 2在什麼情況下仍是框架向量。分享友人
