For example, are hyperbolic trigonometric functions related to rotations in some non-Euclidean geometry or another geometric structure?Thu, 09 Apr 2026 22:05:00 GMThttps://math.stackexchange.com/questions/3650360/why-are-certain-pde-called-elliptic-hyperbolic-or-parabolicWhy are the Partial Differential Equations so named? i.e, elliptical, hyperbolic, and parabolic. I do know the condition at which a general second order partial differential equation becomes these,...Fri, 17 Apr 2026 20:08:00 GMThttps://math.stackexchange.com/questions/5128680/a-notion-of-similarity-in-hyperbolic-geometryWe can have noncongruent polygons which are quasisimilar in the hyperbolic plane; for instance, any two equilateral triangles are quasisimilar. I'm curious how much flexibility there actually is in this notion. In particular: Is every triangle quasisimilar to a triangle with area $1$? More generally, I'm interested in any information about this ...Fri, 10 Apr 2026 04:46:00 GMThttps://math.stackexchange.com/questions/2668264/is-hyperbolic-rotation-really-a-rotationA hyperbolic rotation is a rotation because of its effect on hyperbolic angles! Like the fact circular angles relate to the area of a (circular) wedge, hyperbolic angle is related to the area of a hyperbolic wedge:Wed, 22 Apr 2026 17:32:00 GMThttps://math.stackexchange.com/questions/93765/what-are-the-interesting-applications-of-hyperbolic-geometryBy contrast, in hyperbolic space, a circle of a fixed radius packs in more surface area than its flat or positively-curved counterpart; you can see this explicitly, for example, by putting a hyperbolic metric on the unit disk or the upper half-plane, where you will compute that a hyperbolic circle has area that grows exponentially with the radius.Sun, 19 Apr 2026 15:55:00 GMThttps://math.stackexchange.com/questions/3999593/unifying-the-connections-between-the-trigonometric-and-hyperbolic-functionsThis can even be used to define the hyperbolic functions geometrically, and many authors do the same with the trigonometric functions. Sine and hyperbolic sine are odd, whereas cosine and hyperbolic cosine are even. But sine and cosine are periodic functions, unlike the hyperbolic counterparts.Fri, 17 Apr 2026 02:22:00 GMThttps://math.stackexchange.com/questions/4984480/hyperbolic-manifolds-and-their-fundamental-groupAny manifold is the quotient of its universal cover by its fundamental group, so this statement is a special case of a general principle. So what you are looking for is the statement that a complete simply connected manifold of sectional curvature $-1$ is isometric to the hyperbolic space. This is a basic result in Riemannian geometry and can be found for instance in do Carmo, Manfredo ...Thu, 16 Apr 2026 18:44:00 GMThttps://math.stackexchange.com/questions/1075663/trigonometic-substitution-vs-hyperbolic-substitutionHyperbolic functions describe the same thing but can also be used to solve problem that can't be solved by Euclidean Geometry (where circular functions are sufficient).They can be used to describe Euclidean geometry but basically they are extension of it and used to solve problems from non-Euclidean geometry problems which arise in arise in ...Sat, 18 Apr 2026 13:12:00 GMThttps://math.stackexchange.com/questions/4953623/is-there-a-hyperbolic-rotation-formula-using-hyperbolic-quaternionsWhat do you mean be "hyperbolic rotations"? Do you mean a rotation in hyperbolic space, or a Lorentz boost? These are quite different, as Lorentz boosts actually correspond to translations in hyperbolic space. Rotations in 3D hyperbolic space are, in a certain sense, also represented by the usual quaternions just like in 3D Euclidean space.Fri, 17 Apr 2026 07:51:00 GMThttps://math.stackexchange.com/questions/4812563/is-the-fundamental-group-of-a-closed-orientable-hyperbolic-3-manifold-isomorphIs the fundamental group of a closed orientable hyperbolic $3$-manifold isomorphic to a non-discrete subgroup of $\mathrm {PSL} (2, \mathbb {C})$?
