In this paper we study the effect of a homoclinic tangency in the variation of the topological entropy.
$L^\infty$ solutions for a model of polytropic gas flow with diffusive entropy
Polytropic gas di usive entropy

We establish the global existence of L1 solutions for a model of polytropic gas ow with di usive entropy. The result is obtained by showing the convergence of a class of nite di erence schemes, whic...
The Boltzmann/Shannon entropy as a measure of correlation
The Boltzmann/Shannon entropy correlation
2010/11/1
IIt is demonstrated that the entropy of statistical mechanics and of information theory, $S({\bf p}) = -\sum p_i \log p_i $ may be viewed as a measure of correlation. Given a probability distribution...
