That is, given $A$ local, reduced and one-dimensional, is there a finite extension $A\to B$ where $B$ is Gorenstein?

    $\begingroup$ If the normalization is finite, you could take that. Maybe your situation is a bit more specific than formulated in the question (e.g. things are easier for noetherian rings). Also, you probably want to require some sort of universal property? (I took the liberty of latexifying the question) $\endgroup$ Sep 13, 2014 at 15:28
  • $\begingroup$ I'm trying to avoid the normalization. In particular I'm trying to stick to S2 and seminormal rings only. $\endgroup$ Sep 13, 2014 at 16:59
  • $\begingroup$ In other words, can I get a finite extension of A that is G1, S2, and seminormal? There are ways to make A seminormal and S2. $\endgroup$ Sep 13, 2014 at 17:02
  • $\begingroup$ It is helpful to include such relevant information (and background which can possibly steer the answer in the direction you want) into the question. $\endgroup$ Sep 13, 2014 at 17:49
  • $\begingroup$ +1 for "Gorensteinification". $\endgroup$
