Derivations of orthosymplectic Lie superalgebras

We will describe the derivations of a class of Lie superalgebras generalizing the orthosymplectic Lie superalgebras. Examples are some of the natural subalgebras of differential operators on the (super)circle, recently studied by Kac-Wang-Yan in the classical case and by Cheng-Wang in the supercase. Other examples are Lie algebras graded by root systems of type B and D where our results give a refinement of recent work of Benkart. In particular, we will give a precise description of the derivations of those Lie algebras occurring as the centreless core of extended affine Lie algebras.
