The curvature tensor of almost cosymplectic and almost Kenmotsu (κ,μ,ν)-spaces
(2013)We study the Riemann curvature tensor of (κ,μ, ν)-spaces when they have almost cosymplectic and almost Kenmotsu structures, ...

Polynomial braid combing
(Oxford University Press, 2018)We prove that, for n ≥ 3, the minimal dimension of a model of the classifying space of the braid group Bn, and of the pure braid group Pn, with respect to the family of virtually cyclic groups is n.

Un ejemplo de teoría de bordismo equivalente al PL-bordismo
(Academia de Ciencias Exactas, Físicas, Químicas y Naturales de Zaragoza, 1983)In this paper we define the CPL-manifolds and we prove, by using a desingularization procedure, that these objects give a ...

Cellular covers of local groups
(Springer, 2018-12)We prove that, in the category of groups, the composition of a cellularization and a localization functor need not be idempotent. This provides a negative answer to a question of Emmanuel Dror Farjoun.

Some special types of developable ruled surface
(Hacettepe University (Faculty of Science), 2010)In this study we consider the focal curve Cγ of a space curve γ and its focal curvatures. We characterize some special ...

On certain anti-invariant submanifolds of an S-manifold
(Sociedade Portuguesa de Matemática, 1993)In this paper, the geometry of certain anti-invariant submanifolds of an S-manifold, namely those which are normal to the structure vector fields, is studied.

CR-products of S-manifolds
(Sociedade Portuguesa de Matemática, 1990)In this paper certain CR-submanifolds namely the CR-products, are studied. A characterization theorem is given and the case of CR-products of S-manifolds whose invariant f-sectional curvature is constant, is investigated.

Irreducible triangulations of the once-punctured torus
(Sobolev Institute of Mathematics, 2018)A triangulation of a surface with fixed topological type is called irreducible if no edge can be contracted to a vertex ...

The cellular structure of the classifying spaces of finite groups
(Springer, 2011-08)In this paper we obtain a description of the BZ/p-cellularization (in the sense of Dror-Farjoun) of the classifying spaces of all finite groups, for all primes p.

Basic concepts on Lorentz simmetry and Minkowsky isogeometry by using the MCIM isotopic model
(2004-09)At 1978, R.M. Santilli proposed to generalize the conventional Lie theory by using isotopies. To do it, he considered that ...
