Inmersiones condicionadas de grafos en superficies y seudosuperficies
(1999)
En este traba jo se procede a recapitular resultados conocidos sobre el problema de caracterizar los grafos que admiten inmersiones en super cies y en seudosuper - cies con todos los v ertices en la misma cara y se da ...

A new entropy based summary function for topological data analysis
(Elsevier, 2018)
Topological data analysis (TDA) aims to obtain useful information from data sets using topological concepts. In particular, it may help to infer from nite sample when a con guration space is a manifold. So far, there ...

A multilayer shallow model for dry granular ows with the (I)-rheology: application to granular collapse on erodible beds
(Cambridge University Press, 2016)
In this work we present a multilayer shallow model to approximate the Navier–Stokes equations with the μ(I)μ(I)-rheology through an asymptotic analysis. The main advantages of this approximation are (i) the low cost ...

Central extensions of null-filiform and naturally graded filiform non-Lie Leibniz algebras
(Elsevier, 2017)
In this paper we describe central extensions of some nilpotent Leibniz algebras. Namely, central extensions of the Leibniz algebra with maximal index of nilpotency are classified. Moreover, non-split central extensions ...

Locating a metro line in a historical city centre: application to Sevilla
(Taylor and Francis, 2009)
When constructing a metro alignment under a historical city centre, it is important to generate a cost-effective path while maintaining a minimum distance between the alignment and historical buildings. This paper describes ...

A particular case of extended isotopisms: Santilli's isotopisms
(Hadronic Press, 2006)
Due to a mathematical necessity, it has been proved that it is convenient to give a new interpretation of the multiplicity of Santilli's isounity Ib = Ib(x, v, t, µ, ρ, ...) of any Santilli's isotopism, as a family of ...

On the growth of the Kronecker coefficients
(2017)
We study the rate of growth experienced by the Kronecker coefficients as we add cells to the rows and columns indexing partitions. We do this by moving to the setting of the reduced Kronecker coefficients.

On Filiform and 2-Filiform Leibniz Algebras of Maximum Length
(Heldermann Verlag, 2008)
Leibniz algebras appear as a generalization of Lie algebras. The classification of naturally graded p-filiform Lie algebras is known. Several authors have studied the naturally graded p-filiform Leibniz algebras for any ...

The isoperimetric problem in complete annuli of revolution with increasing Gauss curvature
(Cambridge University Press, 2008)
In this work we describe the isoperimetric regions in complete symmetric annuli of revolution with Gauss curvature non-decreasing from the shortest parallel. This description allows us to complete the classification of ...
