I will give an instroduction to the distribution of discrdtd and dense lattice orbits on homogeneous spaces. An elementary example is the Linear action of SL(2,Z) on the plane. Even for such a simple action, there are many interesting difficult open quenstions. if time permits, I will present some recent progress. The latter is joint work wirh A. Gorodnik and A. Nevo.
