An upper $J$ - Hessenberg reduction of a matrix through symplectic Householder transformations

Ahmed Salam, Haithem Ben Kahla

In this paper, we introduce a reduction of a matrix to a condensed form, the upper $J$ - Hessenberg form, via elementary symplectic Householder transformations, which are rank-one m…
