Abstract
We define global and local Weyl modules for , where is the queer Lie superalgebra and A is an associative commutative unital -algebra. We prove that global Weyl modules are universal highest weight objects in certain category up to parity reversing functor Π. Then with the assumption that A is finitely generated, it is shown that the local Weyl modules are finite dimensional and further they are universal highest map-weight objects in certain category up to Π. Finally, we prove a tensor product property for local Weyl modules.
