| contents | The phenomenon of ergodicity breaking of stochastic dynamics governed by Generalized Langevin Equations (GLE) in the presence of well-behaved exponentially decaying dissipative memory kernels, recently investigated by many authors (Phys. Rev. E {\bf 83} 062102 2011; Phys. Rev. E {\bf 98} 062140 2018; Eur. Phys. J. B {\bf 93} 184 2020),
finds, in the dynamic theory of GLE, its simple and natural explanation, related to the concept of dissipative stability. It is shown that the occurrence of ergodicity breakdown for well-behaved dissipative kernels falls, in general, ouside the region of stochastic realizability, and therefore it cannot be observed in physical systems. |
