Trigonometric Transformations of Sympletic Difference Systems
نویسنده
چکیده
In this paper we show that any symplectic difference system can be transformed into a trigonometric system, using a transformation that preserves oscillatory properties. Necessary and sufficient conditions for nonoscillation of a certain class of trigonometric systems are given, and this result is applied to oscillation theory of Hamiltonian difference systems. 2000 Academic Press

We provide frequency probabilistic analysis of perturbations of physical systems by preparation procedures. We obtained the classification of possible probabilistic transformations connecting input and output probabilities that can appear in physical experiments. We found that so called quantum probabilistic rule is just one of possible rules. Besides the well known trigonometric transformation...
متن کاملLinear representations of probabilistic transformations induced by context transitions
By using straightforward frequency arguments we classify transformations of probabilities which can be generated by transition from one preparation procedure (context) to another. There are three classes of transformations corresponding to statistical deviations of different magnitudes: (a) trigonometric; (b) hyperbolic; (c) hypertrigonometric. Each class is characterized by a perturbation of t...

متن کاملIFS Fractals generated by Affine Transformation with Trigonometric Coefficients and their Transformations
In IFS fractals generated by affine transformations with arbitrary coefficients often there is a lot of chaotic noise. In the present paper we study the effect of related trigonometric coefficients on affine transformations in terms of the IFS fractals generated by them. The use of related trigonometric functions as coefficients reduces the randomness of the scatter and generates meaningful sha...
متن کاملA superfast solver for real symmetric Toeplitz systems using real trigonometric transformations
A new superfast O(n log n) complexity direct solver for real symmetric Toeplitz systems is presented. The algorithm is based on 1. the reduction to symmetric right-hand sides, 2. a polynomial interpretation in terms of Chebyshev polynomials, 3. an inversion formula involving real trigonometric transformations, and 4. an interpretation of the equations as a tangential interpolation problem. The ...
