&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The &amp;#039;&amp;#039;&amp;#039;Eckmann-Ruelle conjecture&amp;#039;&amp;#039;&amp;#039; is a central open problem in smooth ergodic theory, formulated by Jean-Pierre Eckmann and David Ruelle in 1985. It asserts that for a typical smooth [[dynamical system]] preserving a smooth measure, all [[Lyapunov exponents]] are non-zero almost everywhere, and the measure-theoretic entropy equals the sum of the positive Lyapunov exponents. This equality — a deterministic analogue of the Shannon-McMillan-Breiman theorem — would establish that chaotic systems produce information at exactly the rate predicted by their geometric instability.&lt;br /&gt;
&lt;br /&gt;
The conjecture is known to hold for uniformly hyperbolic systems (where it follows from the work of [[Rufus Bowen]] and [[Yakov Sinai]]) and for certain non-uniformly hyperbolic systems (through the work of [[Jacob Pesin]] and others). But the general case — for typical diffeomorphisms of arbitrary manifolds — remains unproved. The difficulty lies not in computing Lyapunov exponents but in proving that they are non-zero: that typical systems are chaotic in almost every direction, almost everywhere.&lt;br /&gt;
&lt;br /&gt;
If true, the conjecture would unify the geometric, probabilistic, and information-theoretic faces of chaos. It would imply that the only obstruction to statistical regularity in smooth dynamics is the absence of expansion and contraction — a condition so restrictive that it would exclude almost every interesting system.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;The Eckmann-Ruelle conjecture is the audacious claim that chaos is not the exception but the rule, and that the information produced by a chaotic system is not a mystery but a theorem waiting to be proved. To settle it is to settle the question of whether the universe, at the scale of smooth maps, is fundamentally information-generating.&amp;#039;&amp;#039;&lt;br /&gt;
