Grassmann–Cayley algebra
From Wikipedia, the free encyclopedia
Grassmann–Cayley algebra is a form of modelling algebra for projective geometry, based on work by German mathematician Hermann Grassmann on exterior algebra, and, subsequently, by British mathematician Arthur Cayley's work on matrices and linear algebra. It is also known as double algebra.
The technique uses subspaces as basic elements of computation, a formalism which allows the translation of synthetic geometric statements into invariant algebraic statements. This can create a useful framework for the modelling of conics and quadrics, among other forms, and tensor mathematics. It also has a number of applications in robotics, particularly for the kinesthetic analysis of manipulators.
