WebDec 12, 2014 · (Somewhat earlier, Andrew Wiles had solved the even more famous ‘Fermat's Last Theorem’ - a problem in number theory - using geometry, albeit geometry of a different flavour.) The fact that the Poincaré Conjecture was equivalent to a problem in geometry had been known for some time prior to Perelman. WebJun 29, 2024 · This polygon satisfies the cycle condition, so by the Poincaré polygon theorem (Theorem 37.6.4), there exists a Fuchsian group \(\Delta \subset {{\,\mathrm{PSL}\,}}_2(\mathbb R )\) generated by the two side pairing elements in P and with fundamental domain T. In this section, we construct this group explicitly and observe …

In mathematics and physics, the Poincaré recurrence theorem states that certain dynamical systems will, after a sufficiently long but finite time, return to a state arbitrarily close to (for continuous state systems), or exactly the same as (for discrete state systems), their initial state. The Poincaré recurrence time is the length of time elapsed until the recurrence. This time may vary greatly depending on the exact initial state and required degree of closeness.
