| Abstract: |
| I will report on progress in the direction of understanding when a boundary
value problem for a weakly elliptic system is well posed, or at least Fredholm solvable,
on a variety of function spaces, and in rather general geometric settings. At the center
of this discussion is the notion of distinguished coefficient tensor, which has a decisive
influence on the Fredholmness and invertibility properties of the boundary layer potential
operators associated with the given system. |
