Relative singular value decomposition and applications to LS-category

E. Macías-Virgós, M. J. Pereira-Sáez, Daniel Tanré

Let $S p (n)$ be the symplectic group of quaternionic $(n \times n)$ -matrices. For any $1 \leq k \leq n$ , an element $A$ of $S p (n)$ can be decomposed in $A= \begin{bmatrix} α&T\cr β&P \…
