Complex case
what about the complex case?

thats described in Banach_space, under the heading Relationship to Hilbert spaces


 * The complex case is now described and sourced in the introduction. Brews ohare (talk) 16:03, 27 June 2010 (UTC)

Sesquilinearity
I think that mentioning the sesquilinear forms is a bit misleading. The sesquilinear form is defined to be linear in the second variable (and conjugate-linear in the first), but the euations in section Complex numbers seem to be true for an inner product that is linear in the first variable (and conjugate-linear in the second one).

Agree

Sesquilinearity can be defined with either convention, but it does seem to be potentially confusing that the first section uses the opposite convention (edited). Adam Marsh (talk) 19:54, 27 February 2018 (UTC)

Why "Polarization"?
Why "polarization"? It "polarizes" what? Or what is "polarizing" in this sense? - Nabla (talk) 17:00, 15 December 2020 (UTC)
