Tunneling for a class of difference operators
Elke Rosenberg (Uni Potsdam)
Sylvie Paycha
This talk (based on joint work with S. Azzali) discusses local linear forms on classical pseudo-differential operators on a closed manifold, and their relevance in index theory.
Local linear forms are spanned by the well-known Wodzicki residue on integer order operators and the somewhat lesser known canonical trace on non-integer order operators.
