I think Yevgeny Zamyatin's We is the best Russian SF I've ever read (and maybe the only Russian SF I've ever read, now that I think about it). Anyway, his metaphors are very mathematical (revolutions are like numbers, infinite; love is like the square root of -1; maybe he was a mathematician). Anyway, I highly recommend it.
