Title: Classical and Quantum stability in theories with many fields

Abstract:

In landscape models, one typically studies and effective potential for many fields, examining stationary points. There has been some work on the likelihood that a particular
stationary point is classically stable, and somewhat less on quantum stability. Some of the results, as we will explain, are puzzling. We will reexamine these questions, finding results
significantly different than some of this earlierwork. Particularly interesting are possible implications for low energy supersymmetry in a landscape framework.
