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, ...

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 ...

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, ...
