In this paper we give the main ideas to show that a real analytic vector field in R3 with a singular point at the origin is locally topologically equivalent to its principal part defined through Newton polyhedra under non-degeneracy conditions.

Feng and Zhu defined the permutation tree structure to achieve a running time of O(n logn) for Hartman and Shamir’s 1.5approximation algorithm for sorting genomes by transpositions. The present work describes the first available implementation of this algorithm using permutation trees. Our analysis of Hartman and Shamir’s algorithm also leads to a modified 1.5-approximation algorithm that achie...

Algebraic dichotomy is a generalization of an exponential (see Lin[?]). This paper gives version Hartman-Grobman linearization theorem assuming that linear system admits algebraic dichotomy, which generalizes the Palmer's theorem. Besides, we prove homeomorphism in Hölder continuous (and has inverse). Comparing with more complicate. The leads us to estimates $\int_{-\infty}^{t}e^{-\alpha(t...

Un teorema bien conocido en dinámica no linear discreta devido a Grobman y Hartman nos dice que un difeomorfismo de clase C1, F:E --> E, con E espacio Banach p punto fijo hiperbólico puede ser topológicamente conjugado para lineal Λ=DF(p) (en una vecindad p). Este trabajo tiene como objetivo llenar todos los vacíos completar las pruebas encontradas el pre-print Belintskii-Rayskin , donde da ...

An electron wave packet tunneling through a barrier has transmission (or ``group delay'') time ${\ensuremath{\tau}}_{g}$ that, for rectangular barrier, is commonly held to become independent of the width $L$ as increases (the McColl-Hartman effect). In present study, it shown that first, effect dependent upon Gamow factor $\ensuremath{\theta}(k)$ vanishes, and only when large; second, triangula...
