Dr. Rodolfo Araya boosts international collaboration in computational and analytical methods

Together with colleagues from France and Southern Cone countries, they hope to consolidate a research group to promote scientific exchange.

 

Dr. Rodolfo Araya Durán, academic of the Faculty of Physical and Mathematical Sciences of the Universidad de Concepción (UdeC) and researcher of the Center for Mathematical Modelling (CMM) of the U. de Chile, recently participated in the scientific event International Conference on Boundary and Interior Layers, Computational and Asymptotic Methods – BAIL 2024 , organized by the Department of Mathematics of the Universidade da Coruña, Spain.

The meeting addressed all aspects of computational and analytical methods for problems whose solution exhibits sharp layers and singular perturbation problems.

The also director of the Center for Research in Mathematical Engineering, CI²MA, presented the talk ‘Stokes Problem with Slip Boundary Conditions‘, in which he reported the results of studies developed in collaboration with his colleagues Alfonso Caiazzo of the Weierstrass Institute for Applied Analysis and Stochastics (WIAS), Germany, and Franz Chouly of the Université de Bourgogne, France.

His participation in this congress -funded by MWC (FB210005) and his Fondecyt Regular project (1211649)- was part of a sabbatical period that Prof. Araya spent at INRENA. Araya developed at INRIA in Paris, mainly to collaborate with the members of the COMMEDIA team (Computational mathematics for bio-medical applications), headed by Miguel Ángel Fernández Varela, whom he met when he was doing his PhD studies at the U. of Paris 6. “We submitted a paper for publication in a WoS journal in the area”, he says.

During his stay, Araya also made contact with the SERENA group (Simulation for the Environment: Reliable and Efficient Numerical Algorithms), directed by Martin Vohralík, which, explains the CI²MA director, “works on a posteriori error estimators, which is one of my lines of research and, from this stay, we had some ideas that we had discussed before”.

“Within this time in Paris, I gave a talk on April 22 in the context of the COMMEDIA group in a meeting with colleagues of the project, which includes several local universities there, and I was also a visiting professor and member of evaluation commissions, among other tasks,” says Araya.

In parallel, Prof. Araya advanced in the joint work with the academic Franz Chouly, who stayed at CI²MA until a few months ago and is currently an academic at the U. of the Republic of Uruguay. “We sent a paper that was accepted in the journal Computer Methods, co-written with him and Gabriel Barrenechea from the U. of Strathclyde (Scotland), who was in France during my stay and then was organizing the meeting in Spain, so I did not have to travel to him,” he explains.

It was also planned that, during the sabbatical, Araya would visit his colleague Frédéric Valentin at the Laboratório Nacional de Computação Científica (LNCC) in Brazil, but this activity was postponed due to logistic problems, however, says the UdeC researcher, “he will come now in October, with funding from my Regular Fondecyt project and I will visit him at the beginning of next year to conclude the work in which we are collaborating”.

Prof. Araya explains that, with his collaborators in France as well as in Uruguay and Brazil, they intend to apply for funding for an international project of the MathAmSud or ECOS-ANID type. “The idea is precisely to encourage the mobility of researchers, but above all of students,” he emphasizes.
