11 p, 300.0 KB Is the product of ccc spaces a ccc space? / Roy, Nina M.
In this expository paper it is shown that Martin's Axiom and the negation of the Continuum Hypothesis imply that the product of ccc spaces is a ccc space. The Continuum Hypothesis is then used to construct the Laver-Galvin example of two ccc spaces whose product is not a ccc space.

19 p, 420.6 KB Bivariant long exact sequences II / Fay, T. H. ; Hardie, K. A.
Given a pair of short exact sequences 1) 0 → X → Y → Z → 0, 0 → A → B → C → 0 in an abelian category A, with sufficiently many projectives and injectives, and given an additive bifunctor T we show that T applied to the pair (1) gives rise to a diagram of a type described by C. [...]

8 p, 192.8 KB A whitehead product for track groups II / Hardie, K. A. ; Jansen, A. V.
Two direct relations are exhibited between the Whitehead product for track groups studied in [4] and the generalized Whitehead product in the sense of Arkowitz. The problem of determining the order of the Whitehead square is posed and some computations given.

11 p, 251.8 KB On the basic character of residue classes / Hilton, P. ; Hooper, J. ; Pedersen, J.
Let t, b be mutually prime positive integers. We say that the residue class t mod b is basic if theie exists n such that tn ≡1 mod b; otherwise t is not basic. In this paper we relate the basic character of t mod b to the quadratic character of t modulo the prime factors of b. [...]

8 p, 206.6 KB Localizing groups with action / Peschke, Georg
When localizing the semidirect product of two groups, the effect on the factors is made explicit. As an application in Topology, we show that the loop space of a based connected CW-complex is a P-local group, up to homotopy, if and only if π1X and the free homotopy groups [S k-1, ΩX], k ≥ 2, are P-local.

17 p, 301.3 KB Qualitative properties of the free-boundary of the reynolds equation in lubrication / Álvarez, S. J.
The hidrodynamic lubrication of a cylindrical bearing is governed by the Reynolds equation that must be satisfied by the preassure of lubricatiog oil. When cavitation occurs we are carried to an elliptic free-boundary problem where the free-boundary separates the lubricated region from the cavited region. [...]

53 p, 1.0 MB Chordal cubil systems / Carbonell, Marc ; Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We classify the phase portraits of the cubic systems in the plane such that they do not have finite critical points, and the critical points on the equator of the Poincaré sphere are isolated and have linear part nonidentically zero.

15 p, 336.8 KB Existence et unicité de la solution pour un systeme de deux E.D.P / Ghannam, Lancem
We give some results on the existence, uniqueness and regularity of a nonlinear evolution system. This system models the viscoelastic behaviour of unicellular marine alga Acetabularia mediterrania when the calcium concentration varies. [...]

10 p, 248.6 KB Rings with zero intersection property on annihilators : zip rings / Faith, Carl
Zelmanowitz [12] introduced the concept of ring, which we call right zip rings, with the defining properties below, whidt are equivalent : (ZIP 1) If the right annihilator X ┴ of a subset X of R is zero,then X,┴ = 0 for a finite subset X, C X. [...]

We give a short proof of the jacobian criterion of formal smoothness using the Lichtenbaum-Schlessinger cotangent complex.

18 p, 417.6 KB Removable sets for holomorphic functions of several complex variables / Stout, Edgar Lee
We show that every closed subset of CN that has finite (2N-2) dimensional measure is a removable set for holomorphic functions, and we obtain a related result on the ball.

Let L be a normal Banach sequence space such that every element in L is the limit of its sections and let E = ind En be a separated inductive limit of locally convex spaces. Then ind L(En) is a topological subspace of L(E).

13 p, 244.1 KB Supersolutions and stabilization of the solution of a nonlinear parabolic system / Elouardi, Hamid ; De Thelin, François
Let us consider a nonlinear parabolic system of the following type: [la fórmula corresponent es troba al document] with Dirichlet boundary conditions and initial data. In this paper, we construct sub-supersolutions of (S), and by use of them, we prove that, for tn→ +∞, the solution of (S) converges to some solution of the elliptic system associated with (S).

8 p, 138.5 KB Fibring the complement of the Fenn-Rolfsen link / Fenn, Roger
In this note it is shown that the complement of the singular linked spheres in four dimensions defined by Fenn and Rolfsen can be fibred by tori. Also a symmetry between the two componente is revealed which shows that the image provides an example of a Spanier-Whitehead duality. [...]
