 n\nTitle: Dirac operators for colour Lie algebras.\n\nAbstract: The noti
 on of colour Lie algebra\, introduced by Ree (1960)\, generalises notion
 s of Lie algebra and Lie superalgebra. From an orthogonal representation
  V of a quadratic colour Lie algebra g\, we give a criteria to construct
  a colour Lie algebra g’ whose bracket extends the bracket of g and the 
 action of g on V. This criteria is used to prove a strange Freudenthal-d
 e Vries formula for basic colour Lie algebras from a Clifford point of v
 iew. Following the use of Dirac operators in representation theory initi
 ated by Parthasarathy in 1972\, we define cubic Dirac operators for colo
 ur Lie algebras and prove a Parthasarathy formula using the same previou
 s criteria.''\n\n\nPlace: Zoom
