WebThe tangent cone has a role in optimization through its polar, the normal cone, N(C, x) = TC, x) = {v * E E *: dy E T(C, x), (v *, y) -_< 0 } (1.2) and through the normal cone's … WebOct 25, 2015 · Examples of tangent cone. In this lecture a tangent cone is defined as the closure of the feasible directions. Definition 9. (Tangent Cone) Let C ⊆ R n be a nonempty set, and let x ∈ C. Then the tangent cone of C at x, denoted by T C ( x), is defined as follows: T C ( x) = c l o s u r e ( F C ( x)). I do not have good visual as to what it ...

WebMay 1, 1985 · Another approach has been to consider tangent cones of various kinds to the graph of ∂f and view these as the graphs of derivative relations. This approach has been pioneered by Aubin [ 5 ], who has observed in particular that the Clarke tangent cone at a point of the graph of ∂ f is the graph of a closed convex process which, if f is ...
