A generalisation of the Phase Kick-Back
(Springer, 2023-03-13)
In this paper, we present a generalisation of the Phase Kick-Back technique, which is central to some of the classical algorithms in quantum computing. We will begin by recalling the Phase Kick-Back technique to then ...

Gröbner bases and the number of Latin squares related to autotopisms of order ≤7
(Elsevier, 2007)
Latin squares can be seen as multiplication tables of quasigroups, which are, in general, noncommutativeand non-associative algebraic structures. The number of Latin squares having a fixed isotopismin their autotopism group ...

Modelos geométricos para el aprendizaje de movimientos en el plano
(Universitat Politécnica de Valencia, 2010)
En geometría moderna, la relación entre la estructura algebraica delos elementos geométricos y la descripción física de estos mismos esa menudo demasiado abstracta para que se pueda explicar ...

Analysis of a fully discrete approximation for the classical Keller–Segel model: Lower and a priori bounds
(Elsevier, 2021)
This paper is devoted to constructing approximate solutions for the classical Keller–Segel model governing chemotaxis. It consists of a system of nonlinear parabolic equations, where the unknowns are the average density ...

Isotopism and isomorphism classes of certain Lie algebras over finite fields
(Springer, 2015)
In the current paper, we study the distribution into isotopism and isomorphism classes of the relevant family FpnFnp of Lie algebras of basis {e1,…,en}{e1,…,en} and nonzero brackets [ei,en]∈⟨e1,…,en−1⟩[ei,en]∈⟨e1,…,en−1⟩ ...

Conjugacy problem for braid groups and Garside groups
(Elsevier, 2003-08-01)
We present a new algorithm to solve the conjugacy problem in Artin braid groups, which is faster than the one presented by Birman, Ko and Lee. This algorithm can be applied not only to braid groups, but to all Garside ...

On the isoperimetric problem in Euclidean space with density
(Springer, 2008)
We study the isoperimetric problemfor Euclidean space endowedwith a continuous density. In dimension one, we characterize isoperimetric regions for a unimodal density. In higher dimensions, we prove existence results and ...

Estimating building construction costs: analysis of the processbasedbudget model (POP Model)
(Pontificia Universidad Católica de Chile, 2016-04)
The recent economic crisis suffered by the Spanish construction sector has brought to light its excessive vulnerability to fluctuations in the real estate market.Overcoming this situation requires to innovate the sector ...

On the r-dynamic coloring of some fan graph families
(Ovidius University Constanta, 2021)
In this paper, we determine the r-dynamic chromatic number of the fan graph Fm,n and determine sharp bounds of this graph invariant for four related families of graphs: The middle graph M(Fm,n), the total graph T(Fm,n), ...

A general approach for the location of transfer points on a network with a trip covering criterion and mixed distances
(Elsevier, 2017)
In this paper we consider a trip covering location model in a mixed planar-network space. An embed- ded network in the plane represents an alternative transportation system in which traveling is fasterthan traveling within ...
