Maps Completely Preserving the Quadratic Operators [PDF]
Sahand Communications in Mathematical Analysis, 2023 Let $\mathcal{A}$ and $\mathcal{B}$ be standard operator algebras on Banach spaces $\mathcal{X}$ and $\mathcal{Y}$, respectively. Let $\phi: \mathcal{A} \rightarrow \mathcal{B}$ be a bijective map.

Quadratic Maps Between Groups [PDF]
Georgian Mathematical Journal, 2009 Abstract The notion of quadratic maps between arbitrary groups appeared at several places in the literature on quadratic algebra. Here a unified extensive treatment of their properties is given; the relation with a relative version of Passi's polynomial maps and groups of degree 2 is established and used to study the structure of the ...

A Class of Quadratic Polynomial Chaotic Maps and its Application in Cryptography
IEEE Access, 2019 At present, the probability density of most chaotic systems is unknown, and the statistical characteristics of chaotic sequences cannot be described by the probability density of chaotic maps. This paper constructs a class of quadratic polynomial chaotic

Quadratic volume-preserving maps [PDF]
Nonlinearity, 1998 We study quadratic, volume preserving diffeomorphisms whose inverse is also quadratic. Such maps generalize the Henon area preserving map and the family of symplectic quadratic maps studied by Moser. In particular, we investigate a family of quadratic volume preserving maps in three space for which we find a normal form and study invariant sets.

A Class of Quadratic Polynomial Chaotic Maps and Their Fixed Points Analysis
Entropy, 2019 When chaotic systems are used in different practical applications, such as chaotic secure communication and chaotic pseudorandom sequence generators, a large number of chaotic systems are strongly required.

Birational Quadratic Planar Maps with Generalized Complex Rational Representations
Mathematics, 2023 Complex rational maps have been used to construct birational quadratic maps based on two special syzygies of degree one. Similar to complex rational curves, rational curves over generalized complex numbers have also been constructed by substituting the ...

THE WAY TO CREATE A PLANE CREMONA MAP FROM ITS CHARACTERISTIC
Tạp chí Khoa học Đại học Đà Lạt, 2022 We describe how to construct a plane Cremona map from its characteristic, which refers to the degree and the list of base-points with their respective multiplicities, and provide some examples of maps of degrees 2 and 3.

Entropy Monotonicity and Superstable Cycles for the Quadratic Family Revisited
Entropy, 2020 The main result of this paper is a proof using real analysis of the monotonicity of the topological entropy for the family of quadratic maps, sometimes called Milnor’s Monotonicity Conjecture.

Iteration of Quadratic Maps on Coquaternions [PDF]
International Journal of Bifurcation and Chaos, 2017 This paper is concerned with the study of the iteration of the quadratic coquaternionic map [Formula: see text], where c is a fixed coquaternionic parameter. The fixed points and periodic points of period two are determined, revealing the existence of a type of sets of these points which do not occur in the classical complex case: sets of nonisolated ...
