Recently several fundamental works have been done in Geometrythe area of the geometry of numbers. Beside Bhargava's revolutionary ideas (an, and of course the contribution of his students), Ergodic theory is a new idea that plays an important role in Modern Geometrymodern geometry of Numbers. Itnumbers which seems to me that several ideas are coming from Margulis and E. LindenstraussLindenstrauss's works.
Here areis a list of workspapers in this area which I think they are extremely interesting and important.
