We present a new kind of one-dimensional attractor, which has not yet been predicted in the non-linear dynamics theory. We consider a non-linear map, which presents typical non-twist manifestations, as isochronous resonances ...

The non-twist standard map occurs frequently in many fields of science specially in modelling the dynamics of the magnetic field lines in tokamaks. Robust tori, dynamical barriers that impede the radial transport among ...

We introduce the labyrinthic standard non-twist map, which is a modified non-twist standard map with an additional perturbation which is a period multiple of the original perturbation period. In phase space this map can ...

De maneira geral, o comportamento dinâmico de sistemas não lineares é caracterizado pela imprevisibilidade e extrema sensibilidade às condições iniciais e aos parâmetros do sistema. A sensibilidade dessas condições pode ...

The super-twisting algorithm (STA) has become the prototype of second-order sliding mode algorithm. It achieves finite time convergence by means of a continuous action, without using information about derivatives of the ...

We introduce the notion of non commutative truncated polynomial extension of an algebra A. We study two families of these extensions. For the first one we obtain a complete classification and for the second one, which we ...
