Web15 de mar. de 2007 · We use L ( H, K) to denote the set of all linear bounded operators from H to K. Also, L ( H) = L ( H, H). For given operators A ∈ L ( H, K) and B ∈ L ( H), we are interested in finding the solution X ∈ L ( H, K) of the equation (1) A * X + X * A = B. This equation is considered for matrices over a finite field (see [7] ).Web15 de nov. de 2024 · We remark that the point of its proof is that A and B are expressed as A = A 1 ⊕ 0 and B = B 1 ⊕ 0 on ran A \oplus \ker A, respectively, and A † = ( A 1) −1 ⊕ 0. Now Theorem FS has an improvement in the following way. Below, let P A be the projection onto ran A, the range of A. Theorem 2.1 Let A and B be positive semidefinite matrices. …
WebFor this class of operators we get the following equation of motion: i h dhA^i dt = h[A;^ H^]i Here the expectation values are taken with arbitrary square integrable functions. Therefore we can re-write this equation as an operator equation: i h dA^ dt = [A;^ H^] If in particular A^ is an observable that commutes with H^, i.e. if [A;^ H^] = 0 ...<1. Several other results involving …

We also know that the derivative operator and one of its inverses, D − 1 = ∫, are both linear operators.
