The Beard "I WAS bald!"), Elaine angrily throws his wig out the window, and the homeless guy picks it up. After the date, Elaine invites Robert to her apartment. Wig-less George tells Jerry he is again himself, and will continue seeing the bald woman; he then tells Jerry, who is going to take the lie detector test, that a lie is not a lie if he believes it. Later, Elaine triumphantly announces to Jerry that Robert has defected from his team and that the conversion went perfectly ("Sex and shopping"). Afterwards, Kramer is still doing police lineups. Jerry takes the lie detector
Reductive Lie algebra generalization of semisimple Lie algebras, and share many properties with them: many properties of semisimple Lie algebras depend only on the fact that they are reductive. Notably, the unitarian trick of Hermann Weyl works for reductive Lie algebras. The associated reductive Lie groups are of significant interest: the Langlands program is based on the premise that what is done for one reductive Lie group should be done for all. The intersection of reductive Lie algebras and solvable Lie algebras is exactly abelian Lie algebras (contrast with the intersection of semisimple and solvable Lie algebras being trivial).
