Dynamics of non-classical interval exchanges [PDF]
, 2010 A natural generalization of interval exchange maps are linear involutions, first introduced by Danthony and Nogueira [Measured foliations on non-orientable surfaces. Ann. Sci. Éc. Norm. Supér. (4) 26(6) (1993), 645–664].

Certifiably optimal rotation and pose estimation based on the Cayley map [PDF]
Int. J. Robotics Res., 2023 We present novel, convex relaxations for rotation and pose estimation problems that can a posteriori guarantee global optimality for practical measurement noise levels. Some such relaxations exist in the literature for specific problem setups that assume

Nicolai maps with four-fermion interactions
Journal of High Energy Physics, 2023 Nicolai maps offer an alternative description of supersymmetric theories via nonlinear and nonlocal transformations characterized by the so-called ‘free-action’ and ‘determinant-matching’ conditions.

Order preserving maps on quantum measurements [PDF]
Quantum, 2022 We study the partially ordered set of equivalence classes of quantum measurements endowed with the post-processing partial order. The post-processing order is fundamental as it enables to compare measurements by their intrinsic noise and it gives grounds

Some results around quadratic maps [PDF]
, 2020 This paper dedicated to study quadratic maps. We present some new operator equalities and inequalities by using quadratic map in the framework of B(H). Applications for particular case of interest are also provided.

Properties of surjective real quadratic maps
, 2020 The properties of surjective real quadratic maps are investigated. Sufficient conditions for the property of surjectivity to be stable under various perturbations are obtained. Examples of surjective quadratic maps whose surjectivity breaks down after an

Quadratic Maps Between Groups [PDF]
gmj, 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 ...

Almost every real quadratic map is either regular or stochastic [PDF]
, 1997 In this paper we complete a program to study measurable dynamics in the real quadratic family. Our goal was to prove that almost any real quadratic map Pc : z t- x2 + c, c c [-2,1/4], has either an attracting cycle or an absolutely continuous invariant ...

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.

On the Dynamics of Cournot Duopoly Game with Governmental Taxes
Complexity, 2022 A quadratic utility function is introduced in this paper to study the dynamic characteristics of Cournot duopoly game. Based on the bounded rationality mechanism, a discrete dynamical map that describes the game’s dynamic is obtained.
