In Memoriam: Jeffrey B. Remmel

It is with great sadness that we report the passing of Jeffrey B. Remmel. Remmel earned his doctorate in mathematics at Cornell University in 1974. He was a student of Anil Nerode. Remmel's dissertation was entitled Co-recursively Enumerable Structures. After completing his Ph.D. Remmel joined the faculty at the University of California at San Diego, where he spent his entire career.

Remmel published more than 300 articles with more than 90 collaborators. About half of his publications were in mainstream mathematical logic and about half were in mainstream algebraic combinatorics. Among these papers were 19 articles in The Journal of Symbolic Logic and 24 articles in the Annals of Pure and Applied Logic. His wide-ranging research interests in logic included computability theory, computable algebra, and computable model theory. His research in logical methods applied to computer science included knowledge representation theory, non-monotonic logics, complexity theory, and hybrid systems. He was co-editor of the two-volume Handbook of Recursive Mathematics, published in 1998, to which he contributed two long survey articles, one on effectively closed sets and one on complexity-theoretic model theory and algebra.

Remmel was adviser to more than 30 Ph.D. students. He served as the Chair of the Mathematics Department, and was the longtime Associate Dean for Physical Sciences at UCSD. He also was a leader in the field of STEM education. He was a founding director of the Science and Math Teacher Initiative (CalTeach) at UCSD. Later he served as chair of the system-wide Committee for CalTeach for the State of California. He also spent several years in private industry as a contributor to commercial hybrid systems software.

Jeff is survived by his wife Paula, and their children Sara-Maria and Christopher. His friends and close collaborators feel deep pain by the enormous and unexpected loss his passing represents.


In Memoriam: Vladimir Voevodsky

Vladimir Voevodsky, a truly extraordinary and original mathematician who made remarkable advances in algebraic geometry, and whose most recent work concerned rewriting the foundations of mathematics to make them suitable for computer proof verification, died at age 51 on September 30, 2017 in Princeton, New Jersey. Voevodsky was Professor in the School of Mathematics at the Institute for Advanced Study, a position he held since 2002.

Born in Moscow on June 4, 1966, Voevodsky earned his Ph.D. in 1992 at Harvard University under David Kazhdan. Voevodsky spent time at Harvard University as a junior fellow in the Harvard Society of Fellows from 1993-96 and as a visiting scholar from 1996-97 and again from 2006-08. He was also a visiting scholar at the Max-Planck Institute in 1996-97, and associate professor at Northwestern University from 1997-98. He was awarded the Fields Medal in 2002 at age thirty-six, shortly after his appointment as Professor in the School of Mathematics. He had spent the prior three years (1998-2001) as a long-term Member.

Voevodsky earned the Fields Medal for developing motivic cohomology, involving new cohomology theories for algebraic varieties, which have provided new insights into number theory and algebraic geometry. Voevodsky was able to handle highly abstract ideas to solve concrete mathematical problems. He had a deep understanding of classical homotopy theory, where the objects considered are flexible, and was able to transpose its methods in the very rigid world of algebraic geometry. This enabled him to construct new cohomology theories for algebraic varieties, which he used to prove the Milnor and Bloch-Kato conjectures, relating K-theory groups of fields and Galois cohomology, which for three decades were the main outstanding problems in algebraic K-theory.

More recently, Voevodsky had worked in type-theoretic formalizations of mathematics and automated proof verification. He was working on new foundations of mathematics based on homotopy-theoretic semantics of Martin-Löf type theories. This led him to introduce a new, very powerful and interesting "univalence'' axiom. Examples of mathematical errors in his own past work and the work of other mathematicians became a growing concern for Voevodsky, and he determined that he needed to use computers to verify his abstract, logical, and mathematical constructions. He applied ideas from homotopy theory to the type theory used in computer proofs, and said that the main goal of his most recent work was "to advance the mathematical theory of dependent type theories to the level where it can be used for rigorous study of the complex type theories that are in use today and of the even more complex ones that will appear in the future.'' Voevodsky formalized much of the mathematics in his newer papers using the proof assistant Coq and the UniMath library of formalized mathematics, of which he was the founder and primary developer.

Voevodsky is survived by his former wife, Nadia Shalaby, their two daughters, Natalia Dalia Shalaby and Diana Yasmine Voevodsky, his aunt, Irina Voevodskaya, and extended family in Russia and around the world. A funeral service will be held in Moscow on December 27th, followed by a mathematical conference in honor of his work on December 28th at the Steklov Mathematical Institute of the Russian Academy of Sciences. The Institute for Advanced Study will convene an international conference on Voevodsky's extraordinary and original work on September 29-30, 2018.


2017 Alonzo Church Award for Outstanding Contributions to Logic

The 2017 Alonzo Church Award for outstanding contributions to logic and computation has been awarded jointly to Samson Abramsky, Martin Hyland, Radha Jagadeesan, Pasquale Malacaria, Hanno Nickau, and Luke Ong for providing a fully-abstract semantics for higher-order computation through the introduction of game models, thereby fundamentally revolutionizing the field of programming language semantics, and for the applied impact of these models. The Alonzo Church Award, presented annually, was established in 2015 by the ACM Special Interest Group for Logic and Computation (SIGLOG), the European Association for Theoretical Computer Science, the European Association for Computer Science Logic, and the Kurt Goedel Society.


In Memoriam: Kosta Dosen

On October 21, 2017 Kosta Dosen died in Belgrade, Serbia, aged 63. He graduated from the University of Belgrade in 1977 and received a doctorate from the University of Oxford in 1981. He became a professor at the Mathematical Institute Belgrade in 1982, was professor at the Department of Computer Science of the University of Toulouse from 1994 to 1998, and held the Chair of Logic in the Philosophical Faculty of the University of Belgrade since 2003. He had visiting professorships at universities including Notre Dame (USA), Montpellier (France) and Tübingen (Germany).

Kosta Dosen's D.Phil. on Logical Constants was supervised by Michael Dummett and Dana Scott. As part of his thesis, and in subsequent publications, he developed a proof-theoretic characterization of logical constants by means of what he called "double-line rules''. This continues to be widely discussed and is one of the major approaches in the debate on what logicality should mean. Working on the proof theory (and partly also model theory) of logics with restricted structural rules, he coined the term "substructural logic'' at a conference in Tübingen in 1990.

The main topic of his intellectual life was the field of categorial proof theory, founded by Joachim Lambek, William Lawvere, and others. Kosta Dosen shaped the development of this field in many respects, in particular with his books Cut Elimination in Categories and Proof-Theoretical Coherence, the latter with Zoran Petrić. He was a strong adherent and promotor of what Dag Prawitz called "general proof theory'', which is the study of proofs as objects in their own right rather than from the point of view of provability. This implied for him that the question of the identity of proofs was the central topic of general proof theory, where he was particularly interested in the relationship between normalization-based and generality-based approaches. In recent years he worked with great passion on Kurt Gödel's work, including unpublished manuscripts in his Nachlass. A critical edition Gödel's Notre Dame course in logic, edited by Milos Adzić and him, has just appeared.

Kosta Dosen was a gifted and dedicated teacher who was an inspiration to students and colleagues alike. His explanations will live on in the pages of his textbook on elementary logic (in Serbian). He will be greatly missed by relatives, friends and colleagues, and all who had the good fortune to know him.
