Uhlhorn theorem

WebWe present an analogue of Uhlhorn’s version of Wigner’s theorem on symmetry transformations for the case of indefinite inner product spaces. This significantly generalizes a result of Van den Broek. Web28 Jan 2024 · The strength and importance of Uhlhorn’s theorem is that it requires that the map keeps the orthogonality of rank-one projections, or equivalently of non-normalized vectors (or rays). A transformation mapping an orthonormal basis onto an orthonormal basis is clearly a unitary or anti-unitary transform; however, this result is far from obvious ...
