Remarques sur la formule sommatoire de Poisson

Jean Kahane, Pierre-Gilles Lemarié-Rieusset (1994)

Studia Mathematica

Similarity:

It is well known that the condition “f ∈ L¹ and f̂ ∈ L¹” is not sufficient to ensure the validity of the Poisson summation formula ∑f(k) = ∑f̂(k). We discuss here a stronger condition " x a f ∈ L p and ξ b f ̂ ∈ L q " and see for which values of a and b the condition is sufficient.

Régularité du temps local brownien dans les espaces de Besov-Orlicz

B. Boufoussi (1996)

Studia Mathematica

Similarity:

Let ( B t , t ≥ 0 ) be a linear Brownian motion and (L(t,x), t > 0, x ∈ ℝ) its local time. We prove that for all t > 0, the process (L(t,x), x ∈ [0,1]) belongs almost surely to the Besov-Orlicz space B M 1 , ∞ 1 / 2 with M 1 ( x ) = e | x | - 1 .

T f -splines et approximation par T f -prolongement

N. Benbourhim, J. Gaches (1993)

Studia Mathematica

Similarity:

We study T f -splines (existence, uniqueness and convergence) in Banach spaces with a view to applications in approximation. Our approach allows, in particular, considering some problems in a more regular domain, and hence facilitating their solution.

Quelques espaces fonctionnels associés à des processus gaussiens

Z. Ciesielski, G. Kerkyacharian, B. Roynette (1993)

Studia Mathematica

Similarity:

The first part of the paper presents results on Gaussian measures supported by general Banach sequence spaces and by particular spaces of Besov-Orlicz type. In the second part, a new constructive isomorphism between the just mentioned sequence spaces and corresponding function spaces is established. Consequently, some results on the support function spaces for the Gaussian measure corresponding to the fractional Brownian motion are proved. Next, an application to stochastic equations...
