Grassmann–Cayley algebra
None
In mathematics , a Grassmann–Cayley algebra is the exterior algebra with an additional product, which may be called the shuffle product or the regressive product. [1] It is the most general structure in which projective properties are expressed in a coordinate-free way. [2] The technique is 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 a form of modeling algebra for use in projective geometry . [ citation needed ]
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 modeling of conics and quadrics among other forms, and in tensor mathematics. It also has a number of applications in robotics , particularly for the kinematical analysis of manipulators.
