Definition:P-Norm

Definition
Let $p \ge 1$ be a real number.

Let $\ell^p$ denote the $p$-sequence space.

Let $\mathbf x = \sequence {x_n} \in \ell^p$.

Then the $p$-norm of $\mathbf x$ is defined as:
 * $\ds \norm {\mathbf x}_p = \paren {\sum_{n \mathop = 0}^\infty \size {x_n}^p}^{1/p}$

 * Definition:Taxicab Norm: for $p = 1$, that is, the $1$-norm


 * By the triangle inequality, the $1$-norm satisfies the.


 * For $p > 1$, Minkowski's inequality states that the $p$-norm satisfies the.


 * The $p$-norm is not to be confused with the $p$-adic norm.
