The Hausdorff Medal

The Hausdorff medal 2019 for the most influential work in set theory in the previous 5 years was awarded to Itay Neeman (UCLA) for his work on the new method of iterating forcing using side conditions and the tree property. The committee cited the following papers for their fundamental contributions and for opening up the new directions of study:

• Forcing with sequences of models of two types, Notre Dame J. Formal Logic, vol. 55 (2014), 265–298
• Two applications of finite side conditions at ω2. Arch. Math. Logic 56 (2017), no. 7-8, 983–1036
• The tree property up to ℵω+1. J. Symb. Log. 79 (2014), no. 2, 429–459

The Hausdorff medal is awarded biennially for the most influential work in set theory published in the five years preceding the medal. For past recipients see the Hausdorff Medal webpage at the ESTS.
