Description
Dear Colleague,
It is our pleasure to invite you to the next talk in our Online Number Theory Seminar, on
11 October (Friday) at 17:00 CET (8:00 PDT, 11:00 EDT, 15:00 GMT, 18:00 Israel Daylight Time, 20:30 Indian Standard Time; already Saturday 2:00 AEDT, 4:00 NZDT)
Speaker: P. Koymans (ETH Zurich)
Title: Value sets of binary forms
Abstract: Given a binary form $F$ with integer coefficients, we define its value set $Val(F)$ to be the set $F(x, y)$ for integers $x, y.$ For two binary forms $F$ and $G,$ what can we say if $Val(F) = Val(G)?$ The goal of this talk is to show how one may give a complete answer to this question. This is joint work with Etienne Fouvry.
