Asymptotic scaling symmetries for nonlinear PDEs
In some cases, solutions to nonlinear PDEs happen to be asymptotically (for large x and/or t) invariant under a group G which is not a symmetry of the equation. After recalling the geometrical meaning of symmetries of differential equations – and solution-preserving maps – we provide a precise definition of asymptotic symmetries of PDEs; we deal in particular, for ease of discussion and physica...
متن کاملAsymptotic Symmetries in General Relativity
The symmetries of flat Minkowski space-time are well known to be described by the Poincare group, and include translations and rotations. On the other hand, the symmetries of an asymptotically flat space-time are described by the infinite-dimensional BondiMatzner-Sachs (BMS) group. This group includes new types of transformations called supertranslations and superrotations, whose physical inter...
متن کاملAsymptotic symmetries of Schrödinger spacetimes
We discuss the asymptotic symmetry algebra of the Schrödinger-invariant metrics in d + 3 dimensions and its realization on finite temperature solutions of gravity coupled to matter fields. These solutions have been proposed as gravity backgrounds dual to non-relativistic CFTs with critical exponent z in d space dimensions. It is known that the Schrödinger algebra possesses an infinite-dimension...
متن کاملAsymptotic pseudounitary stacking operators
Stacking operators are widely used in seismic imaging and seismic data processing. Examples include Kirchhoff datuming, migration, offset continuation, DMO, and velocity transform. Two primary approaches exist for inverting such operators. The first approach is iterative least-squares optimization, which involves the construction of the adjoint operator. The second approach is asymptotic invers...
متن کاملSome Estimates for Rough Multilinear Fractional Integral Operators and Rough Multi-sublinear Fractional Maximal Operators
It is well known that, for the purpose of researching non-smoothness partial differential equation, mathematicians pay more attention to the singular integrals with rough kernel. Moreover, the fractional type operators and their weighted boundedness theory play important roles in harmonic analysis and other fields, and the multilinear operators arise in numerous situations involving product-lik...
