Generalized (κ, µ)-space forms and d-homothetic deformations
(2011)We study the Da-homothetic deformations of generalized (κ, µ)- space forms. We prove that the deformed spaces are again ...

Generalized (κ,μ)-space forms
(Springer, 2013-02)Generalized (κ, µ)-space forms are introduced and studied. We examine in depth the contact metric case and present examples for all possible dimensions. We also analyse the trans-Sasakian case.

Generalized S-space-forms
(2013)We introduce and study generalized S-space-forms. Moreover, we investigate generalized S-space-forms endowed with an additional structure and we obtain some obstructions for them to be S-manifolds

Generalized S-space-forms with two structure vector fields
(De Gruyter, 2010-01)We introduce and study generalized S-space-forms with two structure vector fields. We also present several examples of ...

Generalized Sasakian Space Forms Which Are Realized as Real Hypersurfaces in Complex Space Forms
(MDPI, 2020-05-29)We prove a classification theorem of the generalized Sasakian space forms which are realized as real hypersurfaces in complex space forms.

Generating families of surface triangulations. The case of punctured surfaces with inner degree at least 4
(2015)We present two versions of a method for generating all triangulations of any punctured surface in each of these two families: ...

Generators and closed classes of groups
(Universitat Autònoma de Barcelona, Departament de Matemàtiques, 2021)We show that, in the category of groups, every singly-generated class which is closed under isomorphisms, direct limits, ...

Graph operations and Lie algebras
(Taylor & Francis, 2013)This paper deals with several operations on graphs and combinatorial structures linking them with their associated Lie ...

Graphs associated with nilpotent Lie algebras of maximal rank
(European Mathematical Society, 2003)In this paper, we use the graphs as a tool to study nilpotent Lie algebras. It implies to set up a link between graph ...

Groups which are not properly 3-realizable
(European Mathematical Society, 2012)A group is properly 3-realizable if it is the fundamental group of a compact polyhedron whose universal covering is proper ...

Homogeneity test for functional data
(Taylor & Francis, 2017)In the context of functional data analysis, we propose new two sample tests for homogeneity. Based on some well-known depth ...

Homotopy idempotent functors on classifying spaces
(American Mathematical Society, 2015-02)Fix a prime p. Since their definition in the context of Localization Theory, the homotopy functors PBZ/p and CWBZ/p have ...

Homotopy in digital spaces
(Elsevier, 2003-01-15)The main contribution of this paper is a new “extrinsic” digital fundamental group that can be readily generalized to ...

Induced structures on slant submanifolds of metric F-manifolds
(Indian National Science Academy, 2008-10)We study whether it is possible to obtain an induced structure on a slant submanifold of a metric f-manifold. Moreover, ...

Invariant complex structures on 6-nilmanifolds classification, Frölicher spectral sequence and special Hermitian metrics
(Springer, 2016-01)We classify invariant complex structures on 6-dimensional nilmanifolds up to equivalence. As an application, the behaviour ...

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 ...

Isogroups and isosubgroups
(Real Academia de Ciencias Exactas, Físicas y Naturales, 2003)The main goal of this paper is to give a mathematical foundation, serious and consistent, to some parts of Santilli’s ...
