I suspect that I have found a mistake in a scientific article (within the field of mathematics). Before bothering my colleagues with questions regarding the legitimacy of the content, I would like to know if anyone has corrected the (potential) error before me.
So the question is: Is there anywhere online, where I can find an erratum or similar for articles? Do I have to use specific keywords when searching for such content in databases? Or is it simply not possible to find easily?
