101(B, N) pair — In mathematics, a ( B , N ) pair is a structure on groups of Lie typethat allows one to give uniform proofs of many results, instead of giving a large number ofcase by case proofs. Roughly speaking, it shows that all such groups are similar to… …

103Lorentz invariance in loop quantum gravity — Loop quantum gravity (LQG) is a quantization of a classical Lagrangian field theory. It is equivalent to the usual Einstein Cartan theory in that it leads to the same equations of motion describing general relativity with torsion. As such, it can …
104Hyperboloid structure — Hyperboloid structures are architectural structures designed with hyperboloid geometry. Often these are tall structures such as towers where the hyperboloid geometry s structural strength is used to support an object high off the ground, but… …
105Sylvester's sequence — In number theory, Sylvester s sequence is a sequence of integers in which each member of the sequence is the product of the previous members, plus one. The first few terms of the sequence are::2, 3, 7, 43, 1807, 3263443, 10650056950807,… …
106Even code — A binary code is called an even code if the Hamming weight of all its codewords is even. An even code should have a generator polynomial that include (1+x) minimal polynomial as a product. Furthermore, a binary code is called doubly even if the… …
107Onium compounds — are cations derived by the protonation of mononuclear parent hydrides of elements of the nitrogen group (Group 15), chalcogens (Group 16), or halogens (Group 17), and similar cations derived by the substitution of hydrogen atoms in the former by… …
108Birkhoff polytope — The Birkhoff polytope B n is the convex polytope in R N (where N = n ²) whose points are the doubly stochastic matrices, i.e., the n times; n matrices whose entries are nonnegative real numbers and whose rows and columns each add up to 1.The… …
109Guyou hemisphere-in-a-square projection — The Guyou hemisphere in a square projection is a conformal map projection for the hemisphere (except for four points where the conformality fails). It is an oblique aspect of the Peirce quincuncial projection. When it is used to represent the… …
110Unistochastic matrix — In mathematics, a unistochastic matrix (also called unitary stochastic ) is a doubly stochastic matrix whose entries are the square of the absolute value of some unitary matrix.The detailed definition is as follows. A square matrix B of size n is …
