Title: A Characterization of Projective Varieties of General Type

Abstract: 
Let X be a smooth projective variety over the field of complex numbers. 
X is said to be of general type if and only if the canonical bundle is big. 
In this talk, we will give a new characterization of varieties of general type 
via a specific birational invariant, the pseudo-effective dimension of X. 
In particular, we will prove that X is of general type if and only if the restriction 
of the canonical divisor of X to any movable curve C is ample.
