Dear SIGLOG Members, This year’s July issue of the SIGLOG Newsletter appeared. SIGLOG Newsletter July 2018 In this issue Howard Straubing presents a revisionist history of connections between first-order logic and aperiodic languages in Mikołaj Bojańczyk’s column on Automata. Neil Immerman’s column on Complexity is dedicated to two-variable logics: Emanuel Kieroński, Ian Pratt-Hartmann and Lidia… Continue reading »
Dear SIGLOG Members, This year’s April issue of the SIGLOG Newsletter appeared. SIGLOG Newsletter April 2018 In this issue Diego Figueira surveys research on the satisfiability problem for XPath in Mikołaj Bojańczyk’s column on Automata. In Michael Mislove’s Semantics column, Jane Hillston describes the evolution of stochastic process algebras and their applications. Alin Deutsch, Richard… Continue reading »
The 2018 Alonzo Church Award for Outstanding Contributions to Logic and Computation is given jointly to Tomás Feder and Moshe Y. Vardi for their fundamental contributions to the computational complexity of constraint-satisfaction problems.
Dear SIGLOG Members, This year’s January issue of the SIGLOG Newsletter appeared. SIGLOG Newsletter January 2018 In this issue We start off with Calls for Nominations for two major awards: the Alonzo Church Award for Outstanding Contributions to Logic and Computation, and the Presburger Award for Young Scientists. The Tributes section pays homage to three… Continue reading »
SIGLOG is calling for nominations for The Alonzo Church Award, which should be submitted to catuscia@lix.polytechnique.fr by March 1, 2018. The details of the award and the nomination procedure for this year are described in this post.
Dear SIGLOG Members, This year’s October issue of the SIGLOG Newsletter appeared. We pay tribute to two recently deceased pre-eminent computer scientists: Mike Gordon and Maurice Nivat. The issue features three technical columns. Nathanaël Fijalkow discusses undecidable problems for probabilistic automata in the Automata column edited by Mikołaj Bojańczyk. David Basin, Cas Cremers, Jannik Dreier… Continue reading »
Dear SIGLOG Members, This year’s July issue of the SIGLOG Newsletter appeared. In this issue We announce the winners of this year’s Alonzo Church, LICS Test-of-Time and Kleene Awards! Luc Segoufin surveys the current state of the art in first-order logics with tree-like models in Mikołaj Bojańczyk’s column on Automata. Neil Immerman’s Complexity column… Continue reading »
The 2017 Alonzo Church Award for Outstanding Contributions to Logic and Computation is given jointly to Samson Abramsky, Radha Jagadeesan, Pasquale Malacaria, Martin Hyland, Luke Ong, and Hanno Nickau for providing a fully-abstract semantics for higher-order computation through the introduction of game models, thereby fundamentally revolutionising the field of programming language semantics, and for the… Continue reading »
Dear SIGLOG Members, This year’s April issue of the SIGLOG Newsletter appeared. In this issue Mikołaj Bojańczyk’s Automata column presents a category-theoretic perspective on automata and minimization in an article by Thomas Colcombet and Daniela Petrişan. Mai Gehrke and Andreas Krebs introduce us to Stone duality in Neil Immerman’s column on Complexity. Neha Rungta’s Verification… Continue reading »
The SIGLOG Executive Committee shares the concern of our parent organization, ACM and of other ACM Special Interest Groups about the Executive Order that has led to travel restrictions for citizens from a list of seven countries. We view these restrictions as obstacles to scientific activity and as attacks on the openness and inclusiveness that… Continue reading »
