NettetConvex relaxations of nonconvex functions provide useful bounding information in applications such as deterministic global optimization and reachability analysis. In some situations, the original nonconvex functions may not be known explicitly, but are instead described implicitly by nonlinear equation systems. In these cases, established convex … Nettet2. feb. 2010 · There are a few assumptions that we may make without loss of generality. First, we can assume that the measure μ is nonatomic. (This follows from the fact that the atoms of μ generate an invariant sub-σ-algebra, and Theorems 4.1 and 4.2 are trivially satisfied in the case of atomic measure spaces.). Second, we can assume that the …

NettetI dag · We construct these functions by perturbing the classical recovery sequences for \(E_\varepsilon \).In particular, we need to modify the optimal one-dimensional profile \(q_0\) in such a way that the two factors in the functional \(G_\varepsilon \) concentrate in different regions, so that their product becomes small. We do this by means of a … NettetDefines the Liminf/Limsup of a function taking values in a conditionally complete lattice, with respect to an arbitrary filter. We define Limsup f (Liminf f) where f is a filter taking values in a conditionally complete lattice. Limsup f is the smallest element a such that, eventually, u ≤ a (and vice versa for Liminf f).
