"On groups elementarily equivalent to Tn(R)"

Click here to enter the meeting room


In this talk I will present my joint result with Alexei Miasnikov on the structure of a group elementarily equivalent to the group Tn(R) of all invertible n ✕ n upper triangular matrices, where n ≥ 3 and R is a characteristic zero integral domain. In particular, I will talk about necessary and sufficient conditions for a group to be elementarily equivalent to Tn(R), where R is a characteristic zero algebraically closed field, a real closed field, a number field, or the ring of integers of a number field.
