If is a root system, the Dynkin diagram for the dual root system is obtained from the Dynkin diagram of by keeping all the same vertices and edges, but reversing the directions of all arrows. Thus, we can see from their Dynkin diagrams that B n {\displaystyle B_{n}} and C n {\displaystyle C_{n}} are dual to each other.
Chaos theory is an interdisciplinary area of scientific study and branch of mathematics. It focuses on underlying patterns and deterministic laws of dynamical systems that are highly sensitive to initial conditions. These were once thought to have completely random states of disorder and irregularities. [1]
Conjugate gradient, assuming exact arithmetic, converges in at most n steps, where n is the size of the matrix of the system (here n = 2). In mathematics, the conjugate gradient method is an algorithm for the numerical solution of particular systems of linear equations, namely those whose matrix is positive-semidefinite.

For example, for Newton's method as applied to a function f to oscillate between 0 and 1, it is only necessary that the tangent line to f at 0 intersects the x-axis at 1 and that the tangent line to f at 1 intersects the x-axis at 0. [14] This is the case, for example, if f(x) = x 3 − 2x + 2.
More formally, a metal–organic framework is a potentially porous extended structure made from metal ions and organic linkers. [1][2][3] An extended structure is a structure whose sub-units occur in a constant ratio and are arranged in a repeating pattern.
Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
Dissociative identity disorder [1] [2]; Other names: Multiple personality disorder Split personality disorder: Specialty: Psychiatry, clinical psychology: Symptoms: At least two distinct and relatively enduring personality states, [3] recurrent episodes of dissociative amnesia, [3] inexplicable intrusions into consciousness (e.g., voices, intrusive thoughts, impulses, trauma-related beliefs ...
