An creation to Nonassociative Algebras Richard D. Schafer
The fusion of algebra, research and geometry, and their program to actual global difficulties, were dominant topics underlying arithmetic for over a century. Geometric algebras, brought and labeled via Clifford within the overdue nineteenth century, have performed a famous function during this attempt, as noticeable within the mathematical paintings of Cartan, Brauer, Weyl, Chevelley, Atiyah, and Bott, and in functions to physics within the paintings of Pauli, Dirac and others.
