Topological obstructions to the diagonalisation of pseudodifferential systems
Matteo Capoferri, Grigori Rozenblum, Nikolai Saveliev +1
Given a matrix pseudodifferential operator on a smooth manifold, one may be interested in diagonalising it by choosing eigenvectors of its principal symbol in a smooth manner. We s…

Global and microlocal aspects of Dirac operators: propagators and Hadamard states
Matteo Capoferri, Simone Murro
We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy-compact globally hyperbolic 4-manifolds. We realise the Cauch…
