We consider some nodal aspects of random Gaussian
band-limited functions on a Riemannian manifold.
These include some important examples (such as Random
Spherical Harmonics, "Complex Fubini -Study" and 
"Real Fubini-Study"). Using techniques based on the
powerful methods recently developed by Nazarov and
Sodin we establish the semi-locality and the existence 
of a universal law for a number of properties, such 
as the homeomorphy classes of nodal components,
and their connectivity graph in the high energy limit.
This work is joint with Peter Sarnak.
