Ill-posed problems are those for which small changes in the data, due, for example, to addition of noise, can cause arbitrarily large changes in the solution. The standard approach is to replace such a problem by a nearby well-posed problem. Recent research focuses on exploiting special structure in order to solve larger and harder problems. The first talk in this minisymposium concerns problems with discontinuous coefficients. The second talk considers the central issue in solution of these problems: the choice of the nearby well-posed problem. The last two speakers exploit near-Kronecker product structure or Cauchy-like structure in the ill-posed operator.
