THE FOURTH ROOT OF THE STAGGERED FERMION DETERMINANT Institute for Nuclear Theory University of Washington March 20-21, 2006
The behavior of the fourth root of the staggered fermion determinant in the continuum limit is an important question in contemporary lattice field theory. It poses interesting unresolved theoretical questions and is of immense practical importance because of the computational economy and resulting frequent utilization of staggered fermions in large scale calculations. The purpose of this workshop is to survey the present understanding of the fourth root of the staggered fermion determinant from both theoretical and computational perspectives, and explore future research directions. The workshop is planed around a limited number of pedagogical talks, with the opportunity for extensive informal discussion. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ WORKSHOP AGENDA:
