1. The quantity is the bivector valued commutator product, given by 2. In geometric algebra the rotation is represented by a bivector . 3. In 1907 Silberstein described a bivector approach to the fundamental electromagnetic equations. 4. This is a simple bivector , associated with the simple rotation described. 5. Bivectors and axial vectors are related by orientations for the plane and bivector . 6. Every rotation plane in a rotation has a simple bivector associated with it. 7. The exterior product of two vectors is sometimes called a bivector or a alternating. 8. Similarly, every bivector can be written as the sum of two simple bivectors. 9. First Wilson associates a bivector with an ellipse. 10. The object known as the " bivector " is related to these ideas.
