Inequalities for the frobenius norm
WebThe Frobenius norm and the commutator Albrecht B¨ottchera,1 and David Wenzela,2 aFakulta¨t fu¨r Mathematik, TU Chemnitz, 09107 Chemnitz, Germany Abstract In an earlier paper we conjectured an inequality for the Frobenius norm of the commutator of two matrices. This conjecture was recently proved by Seak-Weng Vong and Xiao-Qing Jin. Web1 aug. 2024 · In this paper, we investigate a generalization of the Böttcher-Wenzel …
