摘要：
The aim of this paper is to define a pair of symplectic Dirac operators (D+, D-) in an algebraic setting motivated by the analogy with the algebraic orthogonal Dirac operators in representation theory. We work in the settings of DOUBLE-STRUCK CAPITAL Z/2-graded quadratic Lie algebras 𝔤� = 𝔨� + 𝔭� and of graded affine Hecke algebras ℍ. In these contexts, we show analogues of the Parthasarathy's formula for [D+, D-] and certain generalisations of the Casimir inequality.
