Derivative of bilinear map
WebA bilinear form H defines a map H#: V → V∗ which takes w to the linear map v → H(v,w). In other words, H#(w)(v) = H(v,w). Note that H is non-degenerate if and only if the map H#: V → V∗ is injective. Since V and V∗ are finite-dimensional vector spaces of the same dimension, this map is injective if and only if it is invertible.

For example, Fig. 2 (A) illustrates a BL system with two linear regions of operation separated by a breakpoint, each region characterised by its own linear stiffness parameter ...
WebIn the mathematical field of differential topology, the Lie bracket of vector fields, also known as the Jacobi–Lie bracket or the commutator of vector fields, is an operator that assigns to any two vector fields X and Y on a smooth manifold M a third vector field denoted [X, Y] . Conceptually, the Lie bracket [X, Y] is the derivative of Y ... WebI wanted to calculate the derivative of a continuous bilinear map B: X 1 × X 2 → Y. (Does anyhere know whether there is a generalisation of the notation L ( X, Y) that you use for the vector space of continuous linear maps to one for bilinear maps B: X 1 × X 2 → Y ?)
