Colloquium di Matematica: Bjorn Poonen (MIT)

Mercoledì 26 Novembre alle ore 16.00, il prof. Bjorn Poonen (MIT) terrà il Colloquium di Matematica dal titolo "Tetrahedra and exponential diophantine equations".

Abstract:
Dehn answered Hilbert's third problem around 1900 by showing that certain tetrahedra are not scissors-congruent to a cube. I will explain progress towards the problem of parametrizing all tetrahedra that are scissors-congruent to a cube. This is based on joint work with Kiran Kedlaya, Alexander Kolpakov, and Michael Rubinstein, and further work of two former MIT undergraduates, A. Anas Chentouf and Yihang Sun.

Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica, Lungotevere Dante 376, aula M1.
