متن کاملThe Commutator Structure of Operator Ideals
Additive commutators of operators belonging to two{sided ideals of B(H) are studied. J){commutators is characterized and found to equal IJ ; B(H)]. It is shown that three commutators are enough in I; B(H)], and that four are enough in I; J ]. Finally, some results about single commutators are proved, for example that every element of the Schatten class C p is a single (C p ; B(H)){commutator if...
متن کاملCommutator Structure of Operator Ideals1
Not much has been known about these spaces except for some special cases. It was known since 1953 that every operator A ∈ B(H) is the sum of two commutators of bounded linear operators [35], [16] while the commutator spaces of Schatten ideals Lp , p > 0, were the subject of several studies over the last 30 years, notably [49], [66], [3], [68], [67], [4], [38] and [18]. Aside from these efforts,...
متن کاملGeneralized Berezin Transform and Commutator Ideals
For a quasi-free module over a function algebra A(Ω), we define an analogue of the Berezin transform and relate this to the quotient of the C*-algebra it generates modulo the commutator ideal. Certainly the best understood commutative Banach algebras are those that consist of all the continuous complex-valued functions on a compact Hausdorff space. Indeed, most self-adjoint phenomena involving ...
متن کاملThe Generalized Berezin Transform and Commutator Ideals
Certainly the best understood commutative Banach algebras are those that consist of all the continuous complex-valued functions on a compact Hausdorff space. Indeed, most self-adjoint phenomena involving them have been thoroughly investigated. In particular, the study of their representation theory as operators on a Hilbert space, which is essentially the spectral theory for normal operators, s...
