Physical parameters of seven field RR Lyrae Stars in Bootes [PDF]
Str\"omgren uvby-beta photometry is reported for the RR Lyrae stars AE, RS, ST, TV, TW, UU, and XX in Bootes. The physical parameters M/Mo, log (L/Lo), M_V, log T_eff and [Fe/H], have been estimated from the Fourier decomposition of the light curves and the empirical calibrations developed for this type of stars.

About the seventh-order Kaup-Kupershmidt equation and its solutions [PDF]
In this letter we obtain exact soliton and periodic solutions to the seventh-order Kaup-Kupershmidt equation. We make use of the Cole-Hopf transformation and two particular rational hyperbolic functions ansatze.

On the maximal function for the generalized Ornstein-Uhlenbeck semigroup [PDF]
In this note we consider the maximal function for the generalized Ornstein-Uhlenbeck semigroup in $\RR$ associated with the generalized Hermite polynomials $\{H_n^{\mu}\}$ and prove that it is weak type (1,1) with respect to $d\lambda_{\mu}(x) = |x|^{2\mu}e^{-|x|^2} dx,$ for $\mu >-1/2$ as well as bounded on $L^p(d\lambda_\mu) $ for $p>1$

Lectures on the three--dimensional non--commutative spheres [PDF]
These are expanded notes for a short course given at the Universidad Nacional de La Plata. They aim at giving a self-contained account of the results of Alain Connes and Michel Dubois--Violette.
