Isometries for Ky Fan Norms Between Matrix Spaces
We characterize linear maps between different rectangular matrix spaces preserving Ky Fan norms.
متن کاملEvolution of the 1984 KKM theorem of Ky Fan
*Correspondence: [email protected]; [email protected] The National Academy of Sciences, ROK, Seoul, 137-044, Korea Department of Mathematical Sciences, Seoul National University, Seoul, 151-747, Korea Abstract Recently we established the Knaster, Kuratowski, and Mazurkiewicz (KKM) theory on abstract convex spaces. In our research, we noticed that there are quite a few generalizations and a...
متن کاملAn extension of the Ky Fan inequality
The aim of this paper is to analyze the weighted KyFan inequality proposed in [11]. A number of numerical simulations involving the exponential weighted function is given. We show that in several cases and types of examples one can imply an improvement of the standard KyFan inequality.
متن کاملOn an identity of Ky Fan
This nice identity was applied in the same paper. Rather surprisingly, this result did not seem to have caught much attention. The object of this short note is to indicate some other consequences of identity (1), which have not been quoted in [5] or [6]. Before going further, and since no proof of this identity is given in [6], we thought worth to give one. The proof goes as follows. Put for an...
متن کاملGeneralizaton of Ky Fan-amir-moéz-horn-mirsky’s Result on the Eigenvalues and Real Singular Values of a Matrix
Ky Fan’s result states that the real parts of the eigenvalues of an n × n complex matrix x are majorized by the eigenvalues of the Hermitian part of x. The converse was established by Amir-Moéz and Horn, and Mirsky, independently. We generalize the results in the context of complex semisimple Lie algebra. The real case is also discussed.
