Speaker:Alex Elgart (VPI) Title: Regularity of the Green Function for a vector valued Anderson System Kerchof 317, 3:30, Wednesday Oct. 24. Abstract: We will decribe a renormalization type procedure that ensures the almost sure regularity of the matrix elements of the resolvent (aka Green function) for a random spin Hamiltonian with a disorder generated by a random magnetic field. This is a joint result with G.-M. Graf.
