Abstract
We present an operational notion of `ground states' in the SK spin glass, that corresponds to the usual definition in short-ranged models such as the EA spin glass. We prove that for any typical coupling realization, every spin configuration is an SK ground state. This result and its proof establish a clear discrepancy between models with infinite-ranged interactions and more realistic spin glasses.
