What Is Hyperbolic Geometry?
(1) Each pair of points can be joined by one and only one straight line segment. (2) Any straight line segment can be indefinitely extended in either direction. (3) There is exactly one circle of any given radius with any given center. (4) All right angles are congruent to one another. (5) If a straight line falling on two straight lines makes the interior angles on the same side less than two ...
متن کاملWhat Is Symplectic Geometry?
In this talk we explain the elements of symplectic geometry, and sketch the proof of one of its foundational results — Gromov’s nonsqueezing theorem — using J-holomorphic curves.
متن کاملWhat is inversive geometry?
Suppose ↵, are concentric. Let a and b denote the radii of ↵ and respectively, and assume a > b. Clearly, such an arrangement of circles i exists only when the centers C1, . . . , Cn of the n circles 1, . . . n are the vertices of a regular n-gon, whose center is the common center O of ↵ and . Consider then a point of tangency T between two circles i and i+1, and the triangle 4OCiT . The edge O...
متن کاملThe Geometry of Environmental Knowledge
Theoretical and empirical work on the geometry of environmental knowledge is discussed. Certain patterns of distanc.e and directional estimates collected from humans have been interpreted as being due to non-metric or non-Euclidean spatial knowledge. I argue that attempts to determine this geometry are inconsistent with existing theoretical models of human knowledge storage and use. Spatial est...
متن کاملWhat is Numerical Algebraic Geometry?
The foundation of algebraic geometry is the solving of systems of polynomial equations. When the equations to be considered are defined over a subfield of the complex numbers, numerical methods can be used to perform algebraic geometric computations forming the area of numerical algebraic geometry. This article provides a short introduction to numerical algebraic geometry with the subsequent ar...
