O objetivo do estudo é analisar Cacau, de Jorge Amado, publicado em 1933, que revela aspectos realismo social: uma tendência estético-literária, vigorava, principalmente, nos anos 1920 e 1930, se caracteriza pelas críticas às estruturas poder capitalista incentivava a opressão política socioeconômica da classe trabalhadora, rural urbana. Por meio ideologia socialista lutas classes, o escritor p...

We use character sums to confirm several recent conjectures of V. I. Arnold on the uniformity of distribution properties of a certain dynamical system in a finite field. On the other hand, we show that some conjectures are wrong. We also analyze several other conjectures of V. I. Arnold related to the orbit length of similar dynamical systems in residue rings and outline possible ways to prove ...

There are three well-known Arnold’s invariants [Formula: see text], and St (Arnold strangeness) for plane curves. Two of them, text] have been successfully quantized. However, the quantization Arnold strangeness remained unrealized. In this paper, we will express a by integrating curvatures multiplied nontrivial densities. The key here is partition function Shumakovitch which reformulates stran...

The Arnold stability criterion suggests that a stationary ow of an ideal incompressible uid is stable if a certain quadratic form is deenite. We show that, in three or more dimensions, this quadratic form is never deenite. Typically the form is indeenite, and the spectrum of the associated Hermitian operator ranges from ?1 to 1. The exceptional case is where the velocity eld is harmonic (soleno...
