Discussion of simple stability criteria for stars with central helium burning

The validity of simple stability criteria for stars with central He-burning used in earlier papers is investigated. The determinant of secular stability for σ=0 is related to quantities defined as far as possible at the surface of the He-core and at the bottom of the envelope. This relation is used to discuss the validity of two intuitive criteria for secular stability.
