Local Invariance via Comparison Functions

چکیده
We consider the ordinary differential equation u′(t) = f(t, u(t)), where f : [a, b] × D → Rn is a given function, while D is an open subset in Rn. We prove that, if K ⊂ D is locally closed and there exists a comparison function ω : [a, b]× R+ → R such that

Rigid invariance as derived from BRS invariance The abelian Higgs model
Consequences of a symmetry, e.g. relations amongst Green functions, are renor-malization scheme independently expressed in terms of a rigid Ward identity. The corresponding local version yields information on the respective current. In the case of spontaneous breakdown one has to define the theory via the BRS invariance and thus to construct rigid and current Ward identity non-trivially in acco...

متن کاملAn invariance kernel representation of ISDS Lyapunov functions
We apply set valued analysis techniques in order to characterize the input–to–state dynamical stability (ISDS) property, a variant of the well known input–to–state stability (ISS) property. Using a suitable augmented differential inclusion we are able to characterize the epigraphs of minimal ISDS Lyapunov functions as invariance kernels. This characterization gives new insight into local ISDS p...
متن کاملCombining persistent homology and invariance groups for shape comparison
In many applications concerning the comparison of data expressed by R-valued functions defined on a topological space X, the invariance with respect to a given group G of self-homeomorphisms of X is required. While persistent homology is quite efficient in the topological and qualitative comparison of this kind of data when the invariance group G is the group Homeo(X) of all selfhomeomorphisms ...
متن کاملLocal scale invariance, conformal invariance and dynamical scaling
Building on an analogy with conformal invariance, local scale transformations consistent with dynamical scaling are constructed. Two types of local scale invariance are found which act as dynamical space-time symmetries of certain non-local free field theories. Physical applications include uniaxial Lifshitz points and ageing in simple ferromagnets. Scale invariance is a central notion of moder...
