Oppenheim conjecture and related problems

Presented by: 
G Margulis Yale University
Date: 
Wednesday 2nd July 2014 - 16:00 to 16:50
Venue: 
INI Seminar Room 1
Abstract: 
Oppenheim conjecture which I proved in mid-eighties says that the set of values at integral points of an irrational indefinite quadratic form in 3 or more variables is dense in R (this is a slightly stronger than the original formulation). I will discuss various approaches to this conjecture and its quantitative generalizations.
