Potential Diagonalizability
Example 1. The matrix ( 0 −1 1 0 ) in M2(R) is not diagonalizable, but it becomes diagonalizable in M2(C) since its characteristic polynomial splits with distinct roots in C[T ]. Example 2. The matrix ( 1 1 0 1 ) is not diagonalizable over any field. Indeed, its only eigenvalue is 1 and its only eigenvectors are scalar multiples of ( 1 0 ) , so there is never a basis of eigenvectors for this ma...
متن کاملSome Results of Sign patterns Allowing Simultaneous Unitary Diagonalizability
Allowing diagonalizability of sign pattern is still an open problem. In this paper, we make a carefully discussion about allowing unitary diagonalizability of two sign pattern. Some sufficient and necessary conditions of allowing unitary diagonalizability are also obtained. Keywords—Sign pattern; Unitary diagonalizability ; Eigenvalue; Allowing diagonalizability
متن کاملA Note on Potential Diagonalizability of Crystalline Representations
Let K0/Qp be a finite unramified extension and GK0 denote the Galois group Gal(Qp/K0). We show that all crystalline representations of GK0 with Hodge-Tate weights ⊆ {0, · · · , p− 1} are potentially diagonalizable.
متن کاملCatalytic Spectrophotometric Determination of Traces of Tellurium (IV)
A Simple, rapid and sensitive method has been developed for determination of trances of tellurium (VI) (0.096-1.250 mg/mL) based on its catalytic effect on the reduction reaction of toluidine blue by sulfide ion at pH 4. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance of the dyestuff at 628 nm by the fixed time method. The detection...
متن کاملContinuous online extraction of HTTP traces from packet traces
To improve the performance of the network and the network protocol it is important to characterize the dominant applications [4, 8, 9, 12, 19, 22, 23]. Only by utilizing data about all events initiated by the Web (including TCP and HTTP events) can one hope to understand the chain of performance problems that current Web users face. Due the the popularity of the Web it is crucial to understand ...
