  It is well-known that, in Linear Dynamics, the most studied class of linear
operators is certainly that of weighted shifts, on the separable Banach spaces
$c_0$ and $\ell^p$, $1 \leq p< \infty$. Over the last decades, the intensive
study of such operators has produced an incredible number of versatile, deep
and beautiful results, applicable in various areas of Mathematics and the
relationships between various important notions, especially concerning chaos
and hyperbolic properties, and the spectrum of weighted shifts are
investigated. In this paper, we investigate the point spectrum of weighted
shifts and, under some regularity hypotheses on the weight sequence, we deduce
the spectrum.
