Recognition

• He was included in the 2019 class of fellows of the American Mathematical Society "for contributions to numerical analysis of domain decompositions within computational mathematics and for incubation through his writing and mentorship of a broad international, creative community of practice applied to highly resolved systems simulations". ^[2]
• The Olof B. Widlund Prize is named in his honor.

Olof B. Widlund Prize

The Olof B. Widlund Prize (formally, the Olof B. Widlund Prize for Excellence in Domain Decomposition Methods) is an award in numerical analysis given in the Domain Decomposition Methods (DDM) community. According to ddm.org, it is a prize for an established scientist recognizing contributions to domain decomposition methods (including theory, algorithms, scalable implementation, applications, and community service). The awardee gives a plenary lecture at the next ddm.org conference and receives a certificate and a cash award of €2500. ^[3]

Recipients have been:

• 2022: Maksymilian Dryja (University of Warsaw). ^{[4] [5]}
• 2024: Charbel Farhat (Stanford University). ^[3]
• 2025: Jan Mandel (University of Colorado). ^[3]

History

According to ddm.org, the prize was established by the Scientific Committee of ddm.org at DD26 (2020) and awarded for the first time at DD27 (Prague, 2022). ^[3]
