| Feb 18, 2013 at 14:21 | comment | added | Loic Rosnay | Sorry for the fuzzy formulation of the question; i thought the terminology "exhaustion by compact set" was clear. Thanks for the hint about sigma-compactness, it is precisely what i meant. Therefore my question is "What general criteria are known to insure sigma-compactness ?" | |

Your question does not seem like a research level question for which this forum is intended to, please see the FAQ. And as Stefan said, also your question is not very clear, please see the how to ask -section. However you might be looking for information about the concept of sigma-compactness, of which information can be found for example from Wikipedia. | |
