Phase diagram of the two-fluid Lipkin model: A "butterfly" catastrophe
(American Physical Society, 2016-03-31)
Background: In the past few decades quantum phase transitions have been of great interest in nuclear physics. In this context, two-fluid algebraic models are ideal systems to study how the concept of quantum phase transition ...

The Heterogeneous Flexible Periodic Vehicle Routing Problem: Mathematical formulations and solution algorithms
(Elsevier, 2022-05)
The aim of this paper is to introduce the Flexible Periodic Vehicle Routing Problem with Heterogeneous Fleet, a variant of the Periodic Vehicle Routing Problem. Flexibility is introduced in service schedules and delivered ...

On the integrability problem for the Hopf-zero singularity and its relation with the inverse Jacobi multiplier
(Elsevier Inc., 2021)
In this paper we use the orbital normal form of the nondegenerate Hopf-zero singularity to obtain necessary conditions for the existence of first integrals for such singularity. Also, we analyze the relation between the ...

Networks, communication and hierarchy: applications to cooperative games
(Birkhäuser, 2021)
Agents participating in different kind of organizations, usually take different positions in some network structure. Two well-known network structures are hierarchies and communication networks. We give an overview of the ...

Error analysis of proper orthogonal decomposition data assimilation schemes with grad–div stabilization for the Navier–Stokes equations
(Elsevier, 2022-09)
The error analysis of a proper orthogonal decomposition (POD) data assimilation (DA) scheme for the Navier–Stokes equations is carried out. A grad–div stabilization term is added to the formulation of the POD method. Error ...

Representabilidad finita por cocientes y operadores
(1998)
"El punto de partida de la memoria es el concepto de representabilidad finita entre espacios de Banach. En 1978, J. Stern propuso un concepto dual al de representabilidad finita dejando abiertas algunas cuestiones. En esta ...

Solving common influence region queries with the GPU
(2013)
In this paper we propose and solve common influence region queries. We present GPU parallel algorithms, designed under CUDA architecture, for approximately solving the studied queries. We also provide and discuss experimental ...

On the barrier-resilience of arrangements of ray-sensors
(2013)
Given an arrangement A of n sensors and two points s and t in the plane, the barrier resilience of A with respect to s and t is the minimum number of sensors whose removal permits a path from s to t such that the path ...
