DESCRIPTION:The theory of random matrices goes back to the 1960's and has 
 found applications in many branches of physics. In condensed matter physic
 s\, random-matrix theory can describe the universal properties of disorder
 ed metals and superconductors\, dependent only on the presence or absence 
 of fundamental symmetries in 10 symmetry classes (the socalled "ten-fold w
 ay"). It was recently discovered that 5 out of these 10 symmetry classes h
 ave a topological invariant\, which identifies distinct states of matter. 
 Some of these topological superconductors and insulators have been realize
 d in the laboratory. In this seminar we will discuss how random-matrix the
 ory can be extended to account for topological properties.
