> Title: On the transference principle in Diophantine approximation
>
> Abstract:
> In 1842, Dirichlet published his famous theorem which became the  
> foundation of Diophantine approximation. The phenomenon he found  
> inspired Liouville to study how well algebraic numbers can be  
> approximated by rationals, and thus, to come up with a method of  
> constructing transcendental numbers explicitly. The development of  
> these ideas led to the concepts of irrationality measure and  
> transcendence measure. Thanks to Minkowski it became clear that many  
> problems arising in the theory of Diophantine approximation could be  
> addressed quite effectively using the tools of geometry of numbers.  
> In particular, the geometric approach naturally offers a wide  
> variety of multidimensional analogues of the concept of  
> irrationality measure — so called Diophantine exponents. In the  
> talk, we will discuss various Diophantine exponents and the geometry  
> that arises when studying them. We will pay special attention to the  
> phenomenon discovered by Khintchine, which he called the  
> transference principle.
