@EE18 \langle and \rangle.

@leslietownes You, too. :(

:(

@leslietownes Though in a lot of cases, those won't really be inner products, but the dual pairing (which devolves to an inner product in spaces which are self-dual. (Not that this really matters).

I personally write my inner products like this $\{\left\{\langle\left[<f,g>\right]\rangle\right\}\}$

just to be clear

more brackets means stronger seal

xander: or maybe it is the inner product that evolves into a dual pairing. hippy music

@leslietownes That isn't how evolution works.

Though it may be the that the inner product is the distant descendant of some common ancestor of the dual pairing.

@leslietownes Actually sorry for perseverating on this Leslie, but I've been searching around and not able to find a wikipage or something like that for this. What term should I be using to learn more about this equivalence between the two possible inner products on this periodic function space?
