For ten points, identify this type of quantity that generally is used to refer to the size or length of an object.
The Bombieri one of these is de ned as5   1 n    1−p p   ni |ai|p i=0for a primenumber p. The Frobenius one of these is equal to  Tr(AAH). This quantity for quaternions is equal to the square root of a quaternion times its quaternion conjugate. The   l1 kind of these is equal to a sum of absolute values, and the most commonly used one of these, the l2 one, is equal to the square root of the sum of the squares of the components of a vector.
