Sparse Approximations for Quaternionic Signals

Our initial idea, due to Philippe Biane, was to find a random matrix model such that the empirical spectral measure would converge to the uniform measure on the unit sphere S 3 ,

At higher time scales, only standard deviation for the critical slowing-down scenario appeared to be suitable, up to 10 year time sample, to identify changes in the

The operators W are called algebraic Heun operators because in the special case of the Jacobi algebra (where Y is the Gauss differential hypergeometric operator) the operator

We prove that the abelian K-surfaces whose endomorphism alge- bra is an indefinite rational quaternion algebra are parametrized, up to isogeny, by the K-rational points of the

In §4 we present our main result describing the Galois action on the isogeny class of an abelian L-surface with QM (A, ı) by means of the map ρ (A,ı,ϕ).. In §5 we discuss about

Abstract In global navigation satellite system (GNSS) receivers, the first signal processing stage is the acquisition, which consists of detecting the received GNSS

Overall, SLEs require MRI documentation, the patient might pro fi t from modi fi cation of her AED-therapy, and all phenotypic manifesta- tions should be considered when diagnosing

Notre travail montre leur fréquence, les difficultés de leur prise en charge et surtout leur pronostic sombre surtout pour les MMC malgré la chirurgie faite à
