Pairs of matrices, one of which commutes with their commutator
Let A, B be n × n complex matrices such that C = AB − BA and A commute. For n = 2, we prove that A, B are simultaneously triangularizable. For n ≥ 3, we give an example of matrices A, B such that the pair (A, B) does not have property L of Motzkin-Taussky, and such that B and C are not simultaneously triangularizable. Finally, we estimate the complexity of the Alp’in-Koreshkov’s algorithm that ...
متن کاملContra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions
The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.
متن کاملA new almost perfect nonlinear function which is not quadratic
Following an example in [13], we show how to change one coordinate function of an almost perfect nonlinear (APN) function in order to obtain new examples. It turns out that this is a very powerful method to construct new APN functions. In particular, we show that the approach can be used to construct “non-quadratic” APN functions. This new example is in remarkable contrast to all recently const...
متن کاملFunctions Which Are Almost Multipliers of Hilbert Function Spaces
We introduce a natural class of functions, the pseudomultipliers, associated with a general Hilbert function space, prove an extension theorem which justifies the definition, give numerous examples and establish the nature of the 1-pseudomultipliers of Hilbert spaces of analytic functions under mild hypotheses. The function 1/z on the unit disc D is almost a multiplier of the Hardy space H: it ...
متن کاملGrafting, Pruning, and the Antipodal Map on Measured Laminations
Grafting a measured lamination on a hyperbolic surface defines a self-map of Teichmüller space, which is a homeomorphism by a result of Scannell and Wolf. In this paper we study the large-scale behavior of pruning, which is the inverse of grafting. Specifically, for each conformal structure X ∈ T (S), pruning X gives a map ML (S) → T (S). We show that this map extends to the Thurston compactifi...
