%0 Journal Article %T Canonical forms of Self-Adjoint Operators in Minkowski Space-time %A Krishan Rajaratnam %J Mathematics %D 2014 %I arXiv %X We classify the possible Jordan canonical forms of self-adjoint operators in Minkowski space-time (in fact in pseudo-Euclidean space, i.e. an indefinite inner product space) and we show how to obtain a Jordan canonical basis which also puts the metric in a canonical form. %U http://arxiv.org/abs/1404.1867v1
