Factorisation of orthogonal projectors
We study the problem of a special factorisation of an orthogonal projector~$P$ acting in the Hilbert space $L_2(\mathbb R)$ with $\dim\ker P<\infty$. In particular, we prove that the orthogonal projector~$P$ admits a special factorisation in the form $P=VV^*$, where $V$ is an isometric upper-tria...
