| Nov 6, 2011 at 12:28 | comment | added | Gro-Tsen | Thanks for pointing out this nice result, which answers a few questions I had in mind. However, I don't think it answers my original question, because the serious problem is for surreals whose length is precisely an epsilon number (e.g., $x\in\mathbf{No}(\varepsilon_0^\omega)$ such that $x=\omega^-x$), and which cannot be "explained" in terms of Hahn series using simpler surreals (Conway calls such surreals "irreducible"). But maybe there is no satisfactory answer to my question. | |
