Almost-linear Zarankiewicz bounds in -semi-equational theories
Hongyi Gou, Mostafa Mirabi, Mihir Mittal +2
We study multipartite hypergraphs definable in -semi-equational theories and prove almost-linear Zarankiewicz bounds in every fixed arity . If is a -semi-equation…
Open Problems in Mathematical Logic
George Barmpalias, Su Gao, Jialiang He +8
These open problems were presented in the Problem Sessions held during the Tianyuan Workshop on Definability and Computation, June 22-26, 2026. The problems are organized into sect…
A nonabelian Brunn-Minkowski inequality II
Yifan Jing, Chieu-Minh Tran
We prove that every unimodular locally compact group of noncompact Lie dimension satisfies the sharp Brunn--Minkowski inequality \[ μ_G(XY)^{1/n}\geμ_G(X)^{1/n}+μ_G(Y)^{1/n…
On Zarankiewicz's bounds for valued vector spaces
Hongyi Gou, Mihir Mittal, Chieu-Minh Tran +1
We establish absolute and relative almost-linear Zarankiewicz bounds for semilinear relations in valued vector spaces. For every fixed arity and description complexity, a $K_{t,\ld…
Categoricity without Power
Jun Le Goh, Chieu-Minh Tran
We prove an analogue of Morley's categoricity theorem where cardinality is replaced by the recursion-theoretic notion of arithmetic degree. We say that a complete arithmetically de…
Large implies henselian
Will Johnson, Chieu-Minh Tran, Erik Walsberg +1
Fix a field . We show that is large if and only if some elementary extension of is the fraction field of a henselian local domain which is not a field. The proof uses a…
On the shatter function of semilinear set systems
Abdul Basit, Chieu-Minh Tran
We show that the shatter function of a semilinear set system on is asymptotic to a polynomial. This confirms, for the structure , a conjecture of…
Measure doubling in unimodular locally compact groups and quotients
Zuxiang Kong, Fei Peng, Chieu-Minh Tran
We consider a (possibly discrete) unimodular locally compact group with Haar measure , and a compact of positive measure with . Let $H…
Of model completeness and algebraic groups
Daniel Max Hoffmann, Piotr Kowalski, Chieu-Minh Tran +1
We show that if G is a split semisimple algebraic group over a model complete field K, then the groups G(K) and G(K)' (the commutator group which is a ``Chevalley group'' as for ex…
Model Theory of Complex Numbers with Polynomial Functions
Benjamin Castle, Chieu-Minh Tran
Let be the set of complex numbers, and let be a collection of complex polynomial maps in several variables. Assuming at least one depends…
Measure doubling of small sets in
Yifan Jing, Chieu-Minh Tran, Ruixiang Zhang
Let be the 3D-rotation group equipped with the real-manifold topology and the normalized Haar measure . Resolving a problem by Breuillard and Green,…
Measure growth in compact semisimple Lie groups and the Kemperman Inverse Problem
Yifan Jing, Chieu-Minh Tran
Suppose is a compact semisimple Lie group, is the normalized Haar measure on , and are measurable. We show that $$μ(A^2)\geq \min\{1, 2μ(A)+ημ(A)(1-…

Suppose is a connected noncompact locally compact group, are nonempty and compact subsets of , is a left Haar measure on . Assuming that is unimodular, and…
A Cauchy-Davenport theorem for locally compact groups
Yifan Jing, Chieu-Minh Tran
We generalize the Cauchy-Davenport theorem to locally compact groups.
A nonabelian Brunn-Minkowski inequality
Yifan Jing, Chieu-Minh Tran, Ruixiang Zhang
Henstock and Macbeath asked in 1953 whether the Brunn-Minkowski inequality can be generalized to nonabelian locally compact groups; questions along the same line were also asked by…

Abdul Basit, Artem Chernikov, Sergei Starchenko +2
A bipartite graph with is semilinear if for some and the edge relation consists of th…

Will Johnson, Chieu-Minh Tran, Erik Walsberg +1
For an arbitrary field and -variety , we introduce the étale-open topology on the set of -points of . This topology agrees with the Zariski topology, Euclide…

Yifan Jing, Chieu-Minh Tran
Let be a connected unimodular group equipped with a (left and hence right) Haar measure , and suppose are nonempty and compact. An inequality by Kemperm…

We classify the stable formulas in the theory of Dense Linear Orders without endpoints, the stable formulas in the theory of Divisible Abelian Groups, and the stable formulas witho…
