Proposition Infinity (generally referred to as "Proposition 8"), which banned same-sex marriage in California in November 2008. The title of the episode is derived from Proposition 8, turning the 8 sideways to create the symbol for infinity (∞), hence "Proposition ∞". Though the episode satirizes arguments for same-sex marriage, it leans favorably toward the idea of allowing same-sex marriage. The theme of the episode revisits the social taboo of robosexual relationships presented in earlier episodes "Space Pilot 3000" and "I Dated a Robot". Openly gay actor George Takei of "Star Trek" fame, who married his partner in California during the debate over
Vanish at infinity Vanish at infinity In mathematics, a function on a normed vector space is said to vanish at infinity if For example, the function defined on the real line vanishes at infinity. More generally, a function formula_4 on a locally compact space (which may not have a norm) vanishes at infinity if, given any positive number formula_5, there is a compact subset formula_6 such that whenever the point formula_8 lies outside of formula_6. In other words, for each positive number formula_5 the set formula_11 is compact. For a given locally compact space formula_12, the set of such functions (where formula_14 is
