Description

 

The Austral Winter Workshop on Microlocal Analysis and Non-elliptic Fredholm Theory will be a two-week intensive workshop on modern microlocal analysis, held at the Australian National University, Canberra, Australia in June-July, 2025. The goal of the workshop is to show how, through microlocal propagation estimates, one can find Fredholm realizations of non-elliptic operators typically encountered in partial differential equations, such as wave operators, Klein-Gordon operators, or Helmholtz operators.
