Math Annotate Platform? For arXiv, a similar system exists (although not that heavily used): scirate3.herokuapp.com |

Ring-theoretic version of a matrix problem Probably too general, but a starting point could be a ring $R$ with an anti-automorphism $t:R\to R$ of order $2$. Then $O(R):=\{x\in U(R)|t(x)=x^{-1}\}$, where $U(R)$ denotes the units of $R$. |

Coinduction and corestriction are quasi-inverse equivalences for comodules? @David White: No, otherwise I would have posted it as an answer. |

if R=M_n(F) then Hom(M,M) = F read the faq, mathoverflow is not the right site to ask |
