Ernst Göhre is also investigated..Similar questions are studied in the case of unitary similarity of pairs (., .) in which . is .-unitary. A broader class of matrices, the “.-normal” matrices, including the .-selfadjoint and .-unitaries will be the topic of Chapter 8.割公牛膨胀 发表于 2025-3-25 13:28:25
Ernst Göhre a Hertz-type contact geometry (a gap between the contacting surfaces in the undeformed state is approximated by an elliptic paraboloid), the theory of local tangential contact of two isotropic bodies was independently developed by Cattaneo [.] and Mindlin [.].

Ernst Göhretal role is played by the construction of a mutually orthogonal set of vectors ., ., . . . , . for which each subset ., . . . , . (. ≤ .) spans the same subspace as ., . . . , .. The well-known Gram—Schmidt process is of this kind. This is also the central idea in the analysis of systems of orthogon
