The solutions to the operator equation TXS − SX T = A in Hilbert C
... generalized the results to Hilbert C∗ -modules, under the condition that ran(S) is contained in ran(T). When T equals an identity matrix or identity operator, this equation reduces to XS ∗ − SX ∗ = A, which was studied by Braden [1] for finite matrices, and Djordjevic [2] for the Hilbert space opera ...

... contain vectors, only the latter pair are true vector equations in the sense that the equations themselves have several components. When going to component notation, all scalar quantities are of course left as they are. Vector quantities, for example E, can always be expanded as E ∑3j & 1 E j x̂ j ...

After this, we study the complex numbers, the number system that contains all of the reals. Following this progression, it makes sense that the next step after studying the ...

We also conclude that each eigenvalue problem actually defines a whole family of “unitary equivalent” problems obtained via isomorphisms of Hilbert spaces. T ...
