Irrational angle

Under the identification of a circlewith R/Z, or with the interval [0, 1]with the boundary points glued together, this map becomes a rotationof a circleby a proportion θof a full revolution (i.e., an angle of 2πθ radians). Since θis irrational, the rotation has infinite orderin the circle groupand the map Tθhas no periodic orbits. See more In the mathematical theory of dynamical systems, an irrational rotation is a map $${\displaystyle T_{\theta }:[0,1]\rightarrow [0,1],\quad T_{\theta }(x)\triangleq x+\theta \mod 1,}$$ where θ is an See more • Circle rotations are examples of group translations. • For a general orientation preserving homomorphism f of S to itself we call a homeomorphism See more • Bernoulli map • Modular arithmetic • Siegel disc • Toeplitz algebra See more Irrational rotations form a fundamental example in the theory of dynamical systems.

WebMar 31, 2024 · It is the ratio of a line segment cut into two pieces of different lengths such that the ratio of the whole segment to that of the longer segment is equal to the ratio of the longer segment to the shorter segment. The origin of this number can be traced back to Euclid, who mentions it as the “extreme and mean ratio” in the Elements. WebAbout the irrational angles : Well, it depends how you measure angles. If you use radians it's rather ovvious that yes, even a square does it (π/4 rad). If you use degrees though, my guess would be that for regular polygons it will always be some fraction of 360º.
