In the realm of scientific endeavor, there emerge luminaries who not only advance the frontiers of knowledge but also inspire and guide generations of scholars. Roland Glowinski, a luminary in every sense, embodies this rare combination of pioneer works and mentorship.
A scion of École polytechnique and a Doctor of Paris VI University (now Sorbonne Université), Roland's journey through academia and research was marked by an unwavering commitment to the highest standards of innovations. Following a start at the "Office de Radiodiffusion-Télévision Française" (the French Television Network), he assumed the mantle of professorship at Paris VI University in 1970.
Swiftly ascending the echelons of recognition, he assumed directorship of the scientific computing laboratory of IRIA, now INRIA, in 1976 and then a series of other esteemed appointments, in particular his directorship of CERFACS in 1992-1994 and the Cullen Professor of Mathematics position at the University of Houston from 2015 until his death in 2022.
The spectrum of Roland's contributions is vast and intricate. Let us coin out some of them (a much more complete description is available at https://comptes-rendus.academie-sciences.fr/mecanique/articles/10.5802/crmeca.169/)
His seminal work on domain decomposition algorithms, stands as a testament to his pioneering spirit. It is this visionary approach that earned him the coveted Cray prize. The field of fictitious domain methods in Lagrangian formulation, explored with the same mastery, enabled Roland to build a very important bridge between theoretical foundations and practical applications.
In the realm of fluid dynamics, Roland's ideas led to the development of robust preconditioners for the Navier-Stokes equations, heralding a new era in computational fluid dynamics. His works on viscoelastic fluids give new iterative methods that allow to grapple with free boundaries problems. Likewise, his contributions to biharmonic problems and compressible fluids have left an indelible mark on the field and had strong applications. In particular, the new methods introduced by Roland for biharmonic problems were implemented at Dassault Aviation and were a model of fruitful scientific cooperation.
Roland's foray into the realm of control theory led to ground breaking strides in hyperbolic problems. He was the first to point out that usual convergent numerical schemes do not converge for the controllability problem: they do not give a control allowing to go from a given state to a desired target. Roland gave the explanation (the appearance in the numerical scheme of spurious high frequencies, which interfere so that the group velocity of the discrete model may vanish or be small) and powerful remedies (a two-grid approach and filtering methods).
Another Roland's captivating achievement lies in his innovative approach to fluid-structure problems, a feat that solved numerically the intricate complexity fluid flow around thousands of suspended solid balls. The elegance of his Lagrangian formulation, where Newton's laws intertwine seamlessly with the variational formulation, stands as a testament to his ingenuity. With this approach there is no need to distinguish the solid balls from the fluid.
Roland Glowinski is also widely acclaimed for his contributions to parallel computing and the finite element method, particularly in the realm of non-linear problem-solving.
Roland Glowinski's journey is dotted with accolades including the Seymour Cray prize, Marcel Dassault prize, the W.T. and Idalia Reid Prize, and his membership in the French Academy of Sciences, the French Academy of Technology and the Academia Europaea.
This collection volume contains the Roland Glowinski works published in the Compte Rendus, works published in the Comptes Rendus which were directly influenced by Roland Glowinski's achievements, and the special issue of the Comptes Rendus Mécanique "The Legacy of Roland Glowinski".
As we turn the pages of this collection volume dedicated to Roland Glowinski, we do so in celebration of a great scientist whose legacy is deeply etched in the annals of applied mathematics and computational mechanics. It is with deep gratitude that we honor a person who shows the path for us all.
