NOTICES

• • The 2022 ASL Election. In the 2022 election, the members of the ASL elected Russell Miller (Queens College, CUNY) and Reed Solomon (University of Connecticut) as Co-Secretary-Treasurers; Samson Abramsky (University College London) and Matthias Aschenbrenner (Vienna) as at-large members of the Executive Committee; and Qi Feng (Tsinghua University) and Rehana Patel (African Institute for Mathematical Sciences) as at-large members of the ASL Council. All terms are for three years beginning January 1, 2023. Many thanks to all those who voted.

• • 2022 Sacks Prize Awarded. The ASL Committee on Prizes and Awards has awarded the 2022 Sacks Prize jointly to Dr. Francesco Gallinaro, currently at the University of Freiburg, and to Dr. Patrick Lutz, currently at the University of California, Los Angeles. Here are the citations by the Committee:

  Francesco Gallinaro received his Ph.D. in 2022 from Leeds University under the joint supervision of Vincenzo Mantova and Dugald Macpherson. His thesis “Around exponential-algebraic closedness” provides further evidence towards the quasi-minimality property of the field of complexes enriched with the exponential map, conjectured by Boris Zilber. For a family of varieties (defined by equations that are dimensionally likely to have solutions), Francesco Gallinaro shows that the Exponential Algebraic Closedness-property holds in the field of complexes, then considers the analogous problem for abelian varieties with their associated exponential maps and finally in the upper half plane endowed with other analytic functions such as the elliptic modular function. His novel approaches also demonstrate a mastery of quite different techniques and are strongly expected to enable further progress.

  Patrick Lutz received his Ph.D. in 2021 from the University of California, Berkeley under the supervision of Theodore A. Slaman. His dissertation “Results on Martin’s Conjecture” contains some of the most substantial progress in decades on Martin’s Conjecture, including a proof of the first part of Martin’s Conjecture for order-preserving functions, and of its analog for regressive functions on the hyperarithmetic degrees. Its methods also open up new possibilities in the study of Martin’s Conjecture. The proofs involve several novel ideas, and a powerful combination of methods from set theory and computability theory, with applications beyond Martin’s Conjecture, including the most significant advance in decades on a question of Sacks about embeddability of continuum-sized partial orders into the Turing degrees.

• • 2022 Shoenfield Prizes Awarded. The ASL Committee on Prizes and Awards has awarded the 2022 Shoenfield Prizes. The Prize for a book is awarded to Sergio Galvan, Paolo Mancosu, and Richard Zach for their book An Introduction to Proof Theory: Normalization, Cut-Elimination, and Consistency Proofs (Oxford University Press, 2021). The Prize for an expository article is awarded to Vasco Brattka for his article “A Galois connection between Turing jumps and limits,” (Logical Methods in Computer Science $\textbf {14}$ , 3 (2018)). Congratulations to the awardees!

• • 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 based 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.

• • ASL membership renewal for 2023 is open. Online renewal for 2023 is available at https://www.cambridge.org/core/membership/asl. Additionally, paper renewal forms are available at http://aslonline.org/membership/individual-membership/, that can be returned by snail mail or email. Members now have the option to choose, for each of our three journals individually, whether to receive print copies or only to have online access to the journal. To make this new arrangement possible, we have reduced the number of options for the term of membership, which will now be available for either a single year or five years. For those who hold multi-year memberships and wish to confirm the expiration date, please log in to your account with Cambridge University Press or send email to [email protected].

  Many logicians, when becoming members of the ASL, opt out of receiving email from Cambridge U.P., which administers the membership program. In such cases, due to European Union regulations regarding opting-out, these members may not receive any electronic notification of the expiration of their memberships, and we know of cases where memberships have lapsed simply because the member was unaware of the expiration date. The ASL is working with CUP to develop a better system, still conforming to the EU regulations. In the meantime, we encourage all those whose memberships expired in 2022, especially those who may have opted out of email, to be careful to renew their memberships in a timely fashion!

• • 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). The deadlines for the 2023 North American Annual Meeting and the 2023 Logic Colloquium have passed. 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/.
