## Nominations Open for 2023 SASTRA Ramanujan Prize

The Shanmugha Arts, Science, Technology, Research Academy (SASTRA), based in the state of Tamil Nadu in South India, has called for nominations for the 2023 SASTRA Ramanujan Prize of $10,000.

The deadline for nominations is July 31, 2023, for a mathematician who has contributed outstanding work in an area of mathematics influenced by the late Indian mathematician Srinivasa Ramanujan. The winner will be a mathematician not exceeding the age of 32: “set at 32 because Ramanujan achieved so much in his brief life of 32 years,” according to the prize organizers.

Each year, the winner is invited to give a talk and receive the prize at an international conference conducted by SASTRA in Kumbakonam, Ramanujan’s hometown, around Ramanujan’s birthday, December 22: held this year December 21–22, 2023.

## Childs Receives Michler Prize

The Association for Women in Mathematics has awarded the 2023–2024 Ruth I. Michler Memorial Prize to **Lauren M. Childs**, associate professor, Department of Mathematics, Virginia Tech.

Childs has been selected to receive the Michler Prize for her research accomplishments in mathematical biology. She will pursue a research project advancing mathematical theory and methods for trait-based models of infectious disease, including integral projection models. Such models also will be used to study the spread of infectious disease—in particular, malaria—and associated population dynamics.

Childs will spend an upcoming semester visiting Cornell University, where she earned her PhD in 2010. She is a member of the American Mathematical Society.

## Wang Awarded 2023 Clifford Prize

**Xieping Wang**, an associate research fellow at the University of Science and Technology of China (USTC) in Hefei, has been selected as the recipient of the 2023 W. K. Clifford Prize for his outstanding contributions to the field of Clifford analysis.

Wang completed his PhD from USTC in 2017. He already has made significant contributions to the field of Clifford analysis, particularly in the area of slice hyperholomorphic functions. His achievements include establishing geometric function theory for slice regular functions over octonions; proving a boundary Schwarz lemma for slice regular self-mappings of the unit ball in the quaternionic space; proving uniqueness of complex geodesics with prescribed boundary value and direction in strongly linearly convex domains; and establishing a Hartog’s type extension theorem for pluriharmonic functions on complex manifolds of dimension -complete Wang’s work has been published in such journals as .*Transactions of the AMS, Mathematische Annalen, Pacific Journal of Mathematics*, and *Journal of Geometric Analysis*.

The W. K. Clifford Prize is an international scientific prize intended to encourage young researchers to compete for excellence in research in theoretical and applied Clifford algebras and their analysis and geometry. Awarded every three years at the International Conference on Clifford Algebras and their Applications in Mathematical Physics (ICCA), the W. K. Clifford Prize will be presented to Wang at the 13th ICCA in Holon, Israel, in June 2023.

## Association for Symbolic Logic Presents Prizes

The Association for Symbolic Logic (ASL) presented the Gerald Sacks Prize and the Shoenfield Prize for 2022.

**Francesco Gallinaro**, Leeds University, and **Patrick Lutz**, University of California, Berkeley, were awarded the Sacks Prize, which is presented annually for the most outstanding doctoral dissertation in mathematical logic. The prize was established to honor the late Professor Gerald Sacks of MIT and Harvard for his unique contribution to mathematical logic, particularly as an adviser to a large number of excellent PhD students. The Sacks Prize became an ASL Prize in 1999; it consists of a cash award plus five years’ free membership in the ASL.

Francesco Gallinaro received his PhD 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), 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 PhD 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 as well as 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.

The Shoenfield Prize, a cash award, is awarded every three years to a book and an expository article for outstanding expository writing in the field of logic. Any new book published during the nine years prior to the award year is eligible; any article published during the six years prior to the award year is eligible.

**Paolo Mancosu, Sergio Galvan**, and **Richard Zach** received the Shoenfield Prize for the book *An introduction to proof theory—normalization, cut-elimination, and consistency proofs* (Oxford University Press, Oxford, 2021. xii+418 pp.)

**Vasco Brattka** received the Shoenfield Prize for the article “A Galois connection between Turing jumps and limits,” *Log. Methods Comput. Sci.* **14** (2018), no. 3, Paper No. 13, 37 pp.

## Ames Awards Winners Announced

The editors and publisher of the *Journal of Mathematical Analysis and Applications* (JMAA) announced the winners of the 2021 Ames Awards last summer.

**Michal Goliński** and **Adam Przestacki** (Adam Mickiewicz University, Poland) were honored for their article “The invariant subspace problem for the space of smooth functions on the real line.” **Alexander Keimer** (University of California, USA) and **Lukas Pflug** (Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany) were honored for their article “On approximation of local conservation laws by nonlocal conservation laws.”

The annual JMAA Ames Awards are in memory of Dr. William F. Ames, editor-in-chief of JMAA from 1991–2006. After Ames’s death in 2008, awards in pure and applied mathematics were established by his relatives to recognize Ames’s many years of outstanding service to the Journal and contributions to the field of applied mathematics. Each award consists of a certificate of merit and a monetary prize of USD $2,500 donated by Elsevier and the AMS.
