Statement

Let nn be a natural number, let Cn\mathbb{C}^{n} be the complex coordinate space, and for a complex number zz let z\overline{z} denote its complex conjugate.

The standard inner product on Cn\mathbb{C}^{n} assigns to each pair u,vCnu,v\in\mathbb{C}^{n} the complex number

u,v=k=1nukvk,\langle u,v\rangle=\sum_{k=1}^{n}\overline{u_{k}}\,v_{k},

where uku_{k} and vkv_{k} are the components of uu and vv and the finite sum is taken in the field of complex numbers.
