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
Hilbert symbol (for "n" prime) used the power residue symbol when "K" has residue characteristic coprime to "n", and was rather complicated when "K" has residue characteristic dividing "n". The Hilbert symbol is (multiplicatively) bilinear: skew symmetric: nondegenerate: It detects norms (hence the name norm residue symbol): It has the "symbol" properties: Hilbert's reciprocity law states that if "a" and "b" are in an algebraic number field containing the "n"th roots of unity then where the product is over the finite and infinite primes "p" of the number field, and where (,) is the Hilbert symbol of the completion at "p".
