The techniques used in [3, 4] are based on a theorem of Mellin... Thus the possible poles of Sj(uj) resp. , zR, the locus consists of only finitely many points

usual metric of Euclidean space .does not satisfy the closure preserving condition, but the metric in the following corollary.. will be more

a a-complete Boolean algebra in its Kantorovitch topology, the analogue for B-metric spaces of the Cantor-Hausdorff completion (20), and the Boolean metrization of

This paper consists of two parts sections 2-5 are concerned with the estimations of the best constant involving the L 2 norm in Wente's inequality, the remainder is devoted to search

Finally, by rescaling suitably the random walk, we retrieve the distribution of the sojourn time in (0, +∞) for the Brownian motion with a possible drift.. This includes of course

Thus our result can be used in adaptive estimation of quadratic functionals in a density model (see for example [4] where white noise is treated), where the theory needs good bounds
