## Dov Gabbay Prize for Logic and Foundations 2024

The *Dov Gabbay Prize for Logic and Foundations* is an international research prize launched on the occasion of Professor Dov Gabbay's 77th birthday. This initiative honours the extraordinary and multi-faceted scientific and editorial work of Dov Gabbay, known in particular for editing an extensive collection of specialized Logic Handbooks.

### 2024 Awardees

ILOAF and the DGP Jury have the great pleasure to announce the winners of the second edition of the
*Dov Gabbay Prize for Logic and Foundations*, whose focus was *Mathematical Logic and its Foundations*:

David Asperó (University of East Anglia, UK) and Ralf Schindler (University of Münster, Germany)

**Our congratulations!**

### Statement of the Jury

Following deliberations at the first round of the Dov Gabbay Prize in 2023 it was determined by the Jury that the emphasis in 2024 would be on mathematical logic (and in 2025 on philosophical logic). A number of very strong nominations were received, and the Jury is pleased to announce that the prize shall be awarded jointly to David Asperó (University of East Anglia, UK) and Ralf Schindler (University of Münster, Germany) for their work in the foundations of set theory, and in particular for their work connecting determinacy principles and so-called strong forcing axioms, both impinging on the nature of the continuum hypothesis (the continuum having size $\aleph_2$ as a consequence from examples of hypotheses in both directions here). Principally the award is given for their solution to the decades old problem in the area by showing that there is a concrete bridge between these two rather different approaches to the foundations of set theory. This work appeared in their paper in the Annals of Mathematics 2021.

David Asperó is well known for his work in set theory, in particular for his contributions to forcing and forcing axioms.

Ralf Schindler has made significant contributions to the theory of inner models of set theory under strong theoretical axioms of infinity and hypotheses of the determinacy of infinite games.
