The question Can one show that ${\gamma^5}^\dagger = \gamma^5$ directly from the anticommutation relations? was recently closed as homework-like. I agree that this is in somewhat of a grey area as far as ontopicness here goes, but I think this is because the core of this question is a maths question:

is it possible to prove such-and-such-a-fact using only this-and-that-hypothesis?

In light of that fact, and because the question is in fact quite good, shouldn't this question be migrated (after appropriate modification if needed) to math.se?

    $\begingroup$ The question seems on-topic, especially because it uses physics notation. Why didn't you vote to reopen? $\endgroup$ – Qmechanic Dec 3 '13 at 1:37

    $\begingroup$ Without information of (anti)hermicity of gamma matrices 0123, actually this question may not be homework level(?). It seems op was trying to prove the problem only using the definition of $\gamma^5$ and anticommuting relations of other gamma matrices.. $\endgroup$ – user26143 Dec 3 '13 at 2:07

    $\begingroup$ The only problem is that you're far more likely to find a physicist able to constructively answer that question than you are a mathematician. I would argue that purely mathematical topics should be on-topic, provided that the underlying math is specialized to physics. $\endgroup$ – Jerry Schirmer Dec 3 '13 at 14:56
