Equivariant measurable liftings
We discuss equivariance for linear liftings of measurable functions. Existence is established when a transformation group acts amenably, as e.g. the Mobius group of the projective line. Since the general proof is very simple but not explicit, we also provi ...
Polish Acad Sciences Inst Mathematics-Impan2015A Dirichlet Analogue Of The Free Monogenic Inverse Semigroup Via Mobius Inversion
The Mobius inversion formula of the free monogenic inverse semigroup is represented by the Mobius function for Cauchy product. In this short note we describe a Dirichlet analogue of this inverse semigroup. ...
Rocky Mountain Mathematics Consortium2011Writing CFT correlation functions as AdS scattering amplitudes
We explore the Mellin representation of conformal correlation functions recently proposed by Mack. Examples in the AdS/CFT context reinforce the analogy between Mellin amplitudes and scattering amplitudes. We conjecture a simple formula relating the bulk s ...
Springer2011Fast Space-Variant Elliptical Filtering Using Box Splines
Michaël Unser, Kunal Narayan Chaudhury
The efficient realization of linear space-variant (non-convolution) filters is a challenging computational problem in image processing. In this paper, we demonstrate that it is possible to filter an image with a Gaussian-like elliptic window of varying siz ...
