On étend aux espaces projectifs à poids le théorème de Beilinson [Funct. Anal. Appl. 12 (1978) 214–216], qui décrit la catégorie derivée bornée des faisceaux cohérents sur ℙ n . Pour obtenir ce résultat on considère, au lieu de la catégorie habituelle des faisceaux cohérents, une certaine catégorie de faisceaux cohérents gradués (qui lui est équivalente dans le cas de ℙ n ).

Beilinson's theorem [Funct. Anal. Appl. 12 (1978) 214–216], which describes the bounded derived category of coherent sheaves on ℙ n , is extended to weighted projective spaces. This result is obtained by considering, instead of the usual category of coherent sheaves, a suitable category of graded coherent sheaves (which is equivalent in the case of ℙ n ).
