• 2023 Sacks Prize. The ASL invites nominations for the 2023 Sacks Prize for the most outstanding doctoral dissertation in mathematical logic. Nominations must be received by September 30, 2023. The Sacks Prize was established to honor the late Professor Gerald Sacks of MIT and Harvard for his unique contribution to mathematical logic, particularly as adviser to a large number of excellent Ph.D. students. The Prize was first awarded in 1994 and became an ASL Prize in 1999. The Fund on which the Prize is based is now administered by the ASL and the selection of the recipient is made by the ASL Committee on Prizes and Awards. The Sacks Prize will consist of a cash award plus five years free membership in the ASL. For general information about the Prize, visit http://aslonline.org/other-information/prizes-and-awards/. Anyone who wishes to make a nomination for the 2023 Sacks Prize should consult the webpage http://aslonline.org/other-information/prizes-and-awards/sacks-prize-recipients/sacks-prize-nominations/ for the precise details of the application process. A brief summary of the procedure is provided here.

Students who defend their dissertations (equivalent to the American doctoral dissertation) between October 1, 2022, and September 30, 2023, are eligible for the Prize this year. This is an international prize, with no restriction on the nationality of the candidate or the university where the doctorate is granted. Nominations should be made by the thesis advisor, and consist of: name of student, title and 1–2 page description of dissertation, date and location of the thesis defense, letter of recommendation from the advisor, an electronic copy of the thesis in pdf form, or the address of a website from which an electronic copy in pdf form can be downloaded, and an independent second letter of recommendation. Nominations and questions about the Prize should be sent to the Committee Chair, Jouko Väänänen; pdf files sent as attachments by email to [email protected] are preferred. The form of such letters and other pertinent details can be found at the website above and need to be read prior to submitting a nomination.

Those wishing to contribute to the Sacks Prize Fund may send contributions to the Business Office: ASL, Dept. of Mathematics, Univ. of Connecticut, 341 Mansfield Road, U-1009, Storrs, CT 06269-1009, USA. All such contributions are tax-deductible within the USA.

• ASL Centennial Fellowship Awarded to Joel Nagloo. The American Mathematical Society awards one Centennial Fellowship in mathematics each year. For 2023–24, this fellowship has been awarded to Prof. Joel “Ronnie” Nagloo of the University of Illinois at Chicago. Prof. Nagloo studies model theory, with a focus on differential algebra. Congratulations to the recipient!

• S. Barry Cooper Prize for 2023. The Association for Computability in Europe has awarded its S. Barry Cooper Prize for the year 2023 to Prof. Rodney G. Downey, of Victoria University in Wellington, New Zealand. The full announcement appears at https://www.acie.eu/2023-s-barry-cooper-prize-awarded-to-rod-g-downey/. This award is given to a researcher who has contributed to a broad understanding and foundational study of computability. The prize will be formally announced at the conference CiE 2023 in Batumi, Georgia, and the award lecture will be delivered during the conference CiE 2024 in Amsterdam.

• Membership Is Now Available to Logicians in China. The ASL is excited to announce that we can once again accept members from the People’s Republic of China. Under PRC regulations, we remain prohibited from mailing journals to members in China. However, we now can offer online access to the ASL journals through Cambridge University Press for members in China. Logicians employed in China who are interested in joining the ASL as new members are encouraged to apply to the ASL Committee on Membership for a free initial two-year outreach membership by emailing their mailing address and professional affiliation to [email protected]. After two years, outreach members should contact Shannon Miller at [email protected] to pay for continued outreach membership at USD 18 per year. Details are available at https://aslonline.org/membership/individual-membership/. Questions about this arrangement can be directed to Shannon Miller, Russell Miller, or Reed Solomon.

Logicians in China, not being on the current membership list, do not receive the Bulletin of Symbolic Logic and may not see these Notices. We therefore encourage all ASL members to spread the news of this welcome change, especially to colleagues based in China.

• Call for Proposals: 2025 North American Annual Meeting. The ASL Committee on Logic in North America requests proposals for the 2025 ASL North American Annual meeting to be held some time during the first five months of 2025. The committee seeks a university somewhere in North America and a local committee to host the meeting and handle the local arrangements. For more information, interested parties should contact the Committee Chair, Tom Scanlon (email: [email protected]), ideally no later than July 15, 2023.

• Open-Access Options for ASL Journals. Authors of research articles in logic, who may wish to consider submitting those articles to the Bulletin of Symbolic Logic, the Journal of Symbolic Logic, or the Review of Symbolic Logic, should be aware that these journals now offer the option of open-access publication. All three journals are now hybrid. They still accept article submissions exactly as before, and they will still publish accepted articles just as before if the author does not opt for open access. However, for authors with mandates to publish open-access articles (or who simply prefer to do so), this option is also available. Details appear at https://www.cambridge.org/core/services/open-access-policies.

• Student Travel Awards: ASL and ASL-Sponsored Meetings. Student members of the ASL may apply for travel grants to ASL and ASL-sponsored meetings. These meetings are identified in the listings below. To be considered for a travel award, please (1) send a letter of application, and (2) ask your thesis supervisor to send a brief recommendation letter. The application letter should be brief (preferably one page) and should include: (1) your name; (2) your home institution; (3) your thesis supervisor’s name; (4) a one-paragraph description of your studies and work in logic, and a paragraph indicating why it is important to attend the meeting; (5) your estimate of the travel expenses you will incur; and (6) (voluntary) indication of your gender and minority status. Women and members of minority groups are strongly encouraged to apply. Application by email is encouraged; put “ASL travel application” in the subject line of your message.

For all of these meetings, applications should be submitted via email to [email protected] or to the ASL Business Office (ASL, Dept. of Mathematics, Univ. of Connecticut, 341 Mansfield Road, U-1009, Storrs, CT 06269-1009, USA). Applications for the 2024 Logic Colloquium and North American Annual Meeting are not yet open. For all other ASL or ASL-sponsored meetings, applications (from student members of the ASL) and recommendations must be received at least three months prior to the start of the meeting. Decisions will be communicated at least two months prior to the meeting.

ASL-sponsored meetings are identified as such among the meetings listed below. Official ASL meetings include the Logic Colloquium, the North American Annual Meeting, the Asian Logic Conference, the Simposio Latino Americano de Lógica Matemática, the ASL Winter Meeting, and the ASL-APA annual joint meeting.

• ASL Sponsorship of Meetings. The ASL often sponsors research meetings and conferences in logic, all over the world. Sponsorship is granted to those meetings that uphold high standards of scholarship and rigor and whose purpose is in concert with the mission of the ASL. Student members of the ASL may apply to the ASL for travel support to attend sponsored meetings, as described above, and a report on each sponsored meeting subsequently appears in the Bulletin of Symbolic Logic. Meeting organizers who are ASL members and wish to request ASL sponsorship of their meetings should do so at least six months before the beginning of the meeting, following the instructions at http://aslonline.org/sponsorship-of-meetings/.
