New examples of generalized Sasakianspaceforms [Article]
(Università di Torino, 2015)In this paper we study when a nonantiinvariant slant submanifold of a generalized Sasakianspaceform inherits such a ...

New relationships involving the mean curvature of slant submanifolds in Sspaceforms [Article]
(Korean Mathematical Society, 2007)Relationships between the Ricci curvature and the squared mean curvature and between the shape operator associated with ...

Normal approximations of regular curves and surfaces [Article]
(Faculty of Sciences and Mathematics, University of Nis, Serbia, 2015)Bezier curves and surfaces are two very useful tools in Geometric Modeling, with many applications. In this paper, we will ...

Null pseudoisotropic Lagrangian surfaces [Article]
(Polish Academy of Sciences, Institute of Mathematics, 2017)In this paper we will show that a Lagrangian, Lorentzian surface M 2 1 in a complex pseudo space form Mf2 1 (4c) is ...

Nullification and cellularization of classifying spaces of finite groups [Article]
(American Mathematical Society, 200704)In this note we discuss the effect of the BZ/pnullification PBZ/p and the BZ/pcellularization CWBZ/p over classifying ...

Nullification functors and the homotopy type of the classifying space for proper bundles [Article]
(Mathematical Sciences Publishers, 200509)Let G be a discrete group for which the classifying space for proper Gactions is finitedimensional. We find a space W ...

Obtaining combinatorial structures associated with lowdimensional Leibniz algebras [Presentation]
(2013)In this paper, we analyze the relation between Leibniz algebras and combinatorial structures. More concretely, we study ...

On abelian subalgebras and ideals of maximal dimension in supersolvable Lie algebras [Article]
(Elsevier, 201402)In this paper, the main objective is to compare the abelian subalgebras and ideals of maximal dimension for finitedimensional ...

On certain antiinvariant submanifolds of an Smanifold [Article]
(Sociedade Portuguesa de Matemática, 1993)In this paper, the geometry of certain antiinvariant submanifolds of an Smanifold, namely those which are normal to the structure vector fields, is studied.

On generalized Sasakianspaceforms [Presentation]
(2004)We study contact metric and transSasakian generalized Sasakianspaceforms. We also give some interesting examples of generalized Sasakianspaceforms by using warped products and conformal changes of metric.

On manifolds with nonhomogeneous factors [Article]
(Springer, 201206)We present simple examples of finitedimensional connected homogeneous spaces (they are actually topological manifolds) ...

On pseudoEinstein hypersurfaces of ℋ2n+s [Article]
(Indian National Science Academy, 199605)In this paper, some properties of the geometry of pseudoEinstein hypersurfaces of the Smanifold ℋ 2n+s are studied and a theorem concerning their principal curvatures is obtained.

On slant submanifolds of neutral Kaehler manifolds [Article]
(Mathematical Society of the Republic of China, 201004)An indefinite Riemannian manifold is called neutral it its index is equal to one half of its dimension and an indefinite ...

On surfaces in digital topology [Presentation]
(1995)In R. Ayala, E. Domínguez, A.R. Francés, A. Quintero, J. Rubio. A Polyhedral Approach to Digital Topology a new framework ...

On the classifying space for proper actions of groups with cyclic torsion [Article]
(De Gruyter, 201401)In this paper we introduce a common framework for describing the topological part of the BaumConnes conjecture for a ...

On the connectivity of skeletons of pseudomanifolds with boundary [Article]
(Mathematical Institute, Academy of Sciences of the Czech Republic, 2002)In this note we show that 1skeletons and 2skeletons of npseudomanifolds with full boundary are (n+ 1)connected graphs and nconnected 2complexes, respectively. This generalizes previous results due to Barnette and Woon.

(Springer, 200910)In this short note we give a simple proof of the existence of an almost contact metric structure on any orientable ...

On the Freudenthal extensions of proper confluent maps [Article]
(University of Houston, 2012)In this paper we study when Freudenthal extensions of proper maps preserve the (weak, semi) confluency. Also the extensions to the Alexandroff onepoint compactificaton are considered.

(Springer, 201201)We present examples of localization functors whose composition with certain cellularization functors is not idempotent, and vice versa.

On the locally finite chain algebra of a proper homotopy type [Article]
(Belgian Mathematical Society, 1996)In the classical paper [AH] AdamsHilton constructed a free chain algebra which is an important algebraic model of a ...
