Web1 de dez. de 2024 · We introduce the concept of non-positive operators with respect to a fixed operator defined between two real normed linear spaces. Significantly, we observe that, in certain cases, it is possible to study such type of operators from a geometric point of view. As an immediate application of our study, we explicitly characterize certain classes …
Webreal inner product spaces. Now, we are going to recall the following Definition1 Let E be a real normed space. E is said to have the Wigner Property if for any real normed space F, and any surjective phase isometry T: E → F, T is phase equivalent to a linear isometry from E to F.
