64 p, 378.5 KB Choquet integrals in potential theory / Adams, David R. (University of Kentucky. Department of Mathematics)
This is a survey of various applications of the notion of the Choquet integral to questions in Potential Theory, i. e. the integral of a function with respect to a non-additive set function on subsets of Euclidean n-space, capacity. [...]

13 p, 168.3 KB Lemme de Fatou pour l'intégrale de Pettis / Amrani, A.
The purpose of this paper is to present Fatou type results for a sequence of Pettis integrable functions and multifunctions. We prove the non vacuity of the weak upper limit of a sequence of Pettis integrable functions taking their values in a locally convex space and we deduce a Fatou's lemma for a sequence of convex weak compact valued Pettis integrable multifunctions. [...]

21 p, 225.6 KB Two weight norm inequality for the fractional maximal operator and the fractional integral operator / Rakotondratsimba, Y.
New su±cient conditions on the weight functions u(:) and v(:) are given in order that the fractional maximal [resp. integral] operator Ms [resp. Is], 0 · s < n, [resp. 0 < s < n] sends the weighted Lebesgue space Lp(v(x) dx) into Lp(u(x)dx), 1 < p < 1. [...]

16 p, 187.4 KB Sampling and interpolation in the Paley-Wiener spaces Lp π, 0 < p ≤ 1 / Flornes, Kristin M. (Norwegian University of Science and Technology. Department of Mathematical Sciences)
Following Beurling's ideas concerning sampling and interpolation in the Paley-Wiener space L∞τ , we find necessary and sufficient density conditions for sets of sampling and interpolation in the Paley-Wiener spaces Lp τ for 0 < p ≤ 1.

12 p, 177.1 KB On the p-rank of an abelian variety and its endomorphism algebra / González, Josep (Escola Universitària Politècnica de Vilanova i la Geltrú. Departament de Matemàtica Aplicada i Telemàtica)
Let A be an abelian variety de¯ned over a ¯nite ¯eld. In this paper,we discuss the relationship between the p-rank of A,r(A), and its endomorphism algebra, End0(A). As is well known, End0(A) determines r(A) when A is an elliptic curve. [...]

12 p, 162.5 KB Solving quadratic equations over polynomial rings of characteristic two / Cherly, Jorgen (Université de Bretagne Occidentale. Department of Mathematics) ; Gallardo, Luis (Université de Bretagne Occidentale. Department of Mathematics) ; Vaserstein, Leonid (Penn State University. Department of Mathematics) ; Wheland, Ethel (University of Akron. Department of Mathematical Sciences)
We are concerned with solving polynomial equations over rings. More precisely, given a commutative domain A with 1 and a polynomial equation an tn + ··· + a0 = 0 with coefficients ai in A, our problem is to find its roots in A. [...]

10 p, 157.1 KB Multidimensional residues and ideal membership / Perotti, Alessandro
Let I(f) be a zero-dimensional ideal in C[z1; : : : ; zn] de¯ned by a mapping f. We compute the logarithmic residue of a polynomial g with respect to f. We adapt an idea introduced by Aizenberg to reduce the computation to a special case by means of a limiting process. [...]

11 p, 159.4 KB A stability result on Muckenhoupt's weights / Kinnunen, J.
We prove that Muckenhoupt's A1-weights satisfy a reverse HÄolder inequality with an explicit and asymptotically sharp estimate for the exponent. As a by-product we get a new characterization of A1-weights.

30 p, 248.4 KB On the Hardy-type integral operators in Banach function spaces / Lomakina, E. ; Stepanov, V.
Characterization of the mapping properties such as boundedness, compactness, measure of non-compactness and estimates of the approximation numbers of Hardy-type integral operators in Banach function spaces are given.

12 p, 151.5 KB Singular measures and the little Bloch space / Cantón, Alicia
Aleksandrov, Anderson and Nicolau have found examples of inner functions that are in the little Bloch space with a specific rate of convergence to zero. As a corollary they obtain positive singular measures defined in the boundary of the unit disc that are simoultaneously symmetric and Kahane. [...]

2 p, 70.7 KB Addendum to "Rings whose modules have maximal submodules" / Faith, Carl
A ring R is right max if every nonzero right R-module has a maximal submodule. In [F1] the author stated several open problems regarding right max rings. Let E be the minimal injective cogenerator of mod-R, and let ¤ = End(ER) be its endomorphism ring. [...]
