Dynamics of a quasi-quadratic map [PDF]
We consider the map given by , where denotes the smallest integer greater than or equal to , and study the problem of finding, for each rational, the smallest number of iterations by that sends it into an integer. Given two natural numbers and , we prove

The Breakup Condition of Shearless KAM Curves in the Quadratic Map [PDF]
We determined the exact location of the shearless KAM curve in the quadratic map and numerically investigate the breakup thresholds of those curves in the entire parameter space.

BERNULLI DIFFERENTIAL EQUATION AND CHAOS
Existence conditions of homoclinic orbits for some systems of ordinary quadratic differential equations with singular linear part are founded. A realization of these conditions guarantees the existence of chaotic attractors at 3-D autonomous quadratic ...

Quadratic rational maps with integer multipliers
17 pages, 4 figures, 6 tablesIn this article, we prove that every quadratic rational map whose multipliers all lie in the ring of integers of a given imaginary quadratic field is a power map, a Chebyshev map or a Lattès map.

On the Content Bound for Real Quadratic Field Extensions
Let K be a finite extension of Q and let S = {ν} denote the collection of K normalized absolute values on K. Let V+K denote the additive group of adeles over K and let K ≥0 c : V + → R denote the content map defined as c({aν }) = Q K ν ∈S ν (aν ) for

Existence of solutions of some quadratic integral equations [PDF]
In this paper we study the existence of continuous solutions of quadratic integral equations. The theory of quadratic integral equations has many useful applications in mathematical physics, economics, biology, as well as in describing real world ...

Persistence of resonant torus doubling bifurcation under polynomial perturbations
Resonant torus doubling bifurcation occurs in discrete maps of three or more dimensions. To date, only three discrete maps have been known to exhibit such bifurcations namely Shilnikov map, generalised Hénon map, and quadratic map.
