Cabaret burlesque, drag shows, or a solo vocalist with a pianist, as well as the venues which offer this entertainment, are often advertised as cabarets. The first known use of the word "cabaret" was in 1655. It is may be derived from the Middle Dutch "cambret", itself probably derived from an earlier form of "chambrette", little room, or from the Norman French "chamber" meaning tavern, itself derived from the Late Latin word "camera" meaning an arched roof. The word "cabaret" came to mean "a restaurant or night club" by 1912. The word "cabaret" was originally Flemish (and possibly Picard before that).
Picard group sequence gives basic information on the Picard group. The name is in honour of Émile Picard's theories, in particular of divisors on algebraic surfaces. and since formula_6 we have formula_7 because formula_8 is contractible, then formula_9 and we can apply the Dolbeault isomorphism to calculate formula_10 by the Dolbeault-Grothendieck lemma. The construction of a scheme structure on (representable functor version of) the Picard group, the Picard scheme, is an important step in algebraic geometry, in particular in the duality theory of abelian varieties. It was constructed by , and also described by and . The Picard variety is dual to
