35 p, 682.5 KB Integral formulas on projective space and the radon transform of Gindikin-Henkin-Polyakov / Berndtsson, Bo
We construct a variant of Koppelman's formula for (0, q)-forms with values in a line bundle, 0 (l), on projective space. The formula is then applied to a study of a Radon transform for (0, q) -forms, introduced by Gindikin-Henkin-Polyakov. [...]

5 p, 143.9 KB Infinite locally finite groups of type PSL(2, K) or Sz(K) are not minimal under certain conditions / Otal, Javier (Universidad de Zaragoza. Departamento de Matemáticas) ; Peña, Juan Manuel (Universidad de Zaragoza. Departamento de Matemáticas)
In classifying certain infinite groups under minimal conditions it is needed to find non-simplicity criteria for the groups under consideration. We obtain some of such criteria as a consequence of the main result of the paper and the classification of finite simple groups.

3 p, 94.0 KB Existencia de inyectores en grupos finitos respecto de ciertas clases de fitting / Iranzo, M. J. ; Pérez Monasor, Francisco
In this paper we prove that all finite groups have F-injectors with respect to a saturated and extensible Fitting formation F.

18 p, 488.6 KB Evaluating a p-th order cohomology operation / Harper, J. ; Zabrodsky, A.
A certain p-th order cup product is detected by a p-th order cohomology operation . The result is applied to finite H-spaces, to show that several properties of compact Lie groups do not hold for arbitrary torsion free finite H-spaces.

7 p, 190.0 KB Some results in representable banach spaces / Canela, Miguel A.
Some results are presented, concerning a class of Banach spaces introduced by G. Godefroy and M. Talagrand, the representable Banach spaces. The main aspects considered here are the stability in forming tensor products, and the topological properties of the weak* dual unitball.

3 p, 71.3 KB A representation theorem for certain boolean lattices / Ríos Montes, José
Let R be an associative ring with 1 and R-tors the complete brouwerian lattice of all hereditary torsion theories on the category of left R-modules. A well known result asserts that R is a left semiartinian ring iff R-tors is a complete atomic boolean lattice. [...]

7 p, 217.1 KB On equivariant deformation of maps / Vidal, Antonio
We work in the smooth category: manifolds and maps are meant to be smooth. Let G be a finite group acting on a connected closed manifold X and f an equivariant self-map on X with flA fixpointfree, where A is a closed invariant submanifold of X with codim A >- 3. [...]
