Log-plurigenera in stable families of surfaces
János Kollár
We study the flatness of log-pluricanonical sheaves on stable families of surfaces.
Log-plurigenera in stable families
János Kollár
We study the flatness of log-pluricanonical sheaves on stable families of varieties. v2: many changes in presentation, results unchanged.
Upper Bounds on the Quantifier Depth for Graph Differentiation in First-Order Logic
Sandra Kiefer, Pascal Schweitzer
We show that on graphs with n vertices, the 2-dimensional Weisfeiler-Leman algorithm requires at most O(n^2/log(n)) iterations to reach stabilization. This in particular shows that…
Semi-stable extensions over 1-dimensional bases
János Kollár, Johannes Nicaise, Chenyang Xu
Given a family of Calabi-Yau varieties over the punctured disc or over the field of Laurent series, we show that, after a finite base change, the family can be exended across the o…
Curve-rational functions
János Kollár, Wojciech Kucharz, Krzysztof Kurdyka
Let be a subset of the set of real points of a real algebraic variety . We investigate which functions are the restrictions of rational functions on …
The dual complex of Calabi--Yau pairs
János Kollár, Chenyang Xu
A log Calabi--Yau pair consists of a proper variety and a divisor on it such that is numerically trivial. A folklore conjecture predicts that the dual complex of $D…
