Supersymmetry and the generalized Lichnerowicz formula
Thomas Ackermann
A classical result in differential geometry due to Lichnerowicz [8] is concerned with the decomposition of the square of Dirac operators defined by Clifford connections on a Cliffo…

A Note on the Wodzicki Residue
Thomas Ackermann
In this note we explain the relationship of the Wodzicki residue of (certain powers of) an elliptic differential operator \ acting on sections of a complex vector bundle \ ov…
