(1≤.≤+∞) analogs, covering most of the expected cases of the convergence of positive linear operators with rates to the unit. In the same inequality we achieve to combine different ..-norms.

Stable Models in Testable Asset Pricing,his field, or from a direct proof. For the APT, we study an asymptotic stable version and we provide an original testing procedure. In both cases, our work is possible after we have established mathematical properties concerning the structure of spaces of symmetric Pareto-stable random variables.

On Some Shift-Invariant Integral Operators, Multivariate Case,o very recently, they studied the same property over ℝ, along with other characteristics, for some particular family of general shift-invariant integral operators. Here a generalization to ℝ., d ≥ 1, is given and everything can be transferred there from the univariate case. Namely, a general positiv

Multivariate Probabilistic Wavelet Approximation,tivariable distribution functions. The degree of this approximation is estimated by establishing some sharp local Jackson type inequalities. We extend the results for distributions of stochastic processes and unbounded measures.
