WebDifferentiability of Bilinear Maps S Kumaresan [email protected] 9 March 2024 Definition 1. Let Vi, i ˘1,2 and W be vector spaces over a field F. A map f: V1 £V2!W is bilinear if f is linear in each of its variables when the other variable is fixed: v1 7!f (v1,v2) from V1 to W is linear for any fixed v2 2V2 and v2 7!f (v1,v2) from V2 to W is linear for … WebThe map Tis unique, denoted df(x 0) and called ‘di erential (or ‘derivative’) of fat x 0. Another notation for this is: f(x 0 + h) f(x 0) = df(x 0)[h] + o(h) (pronounced ‘little oh of h’). Remarks. 1. If f is continuous at x 0, it is easy to see that when f is di erentiable at x 0 we have df(x 0) 2L(E;F): the di erential is a bounded ...
