Equivalence of nontrivial blocks of Lie superalgebras of type W(n)

Let $W(n)$ be the Lie superalgebra of type $W(n)$, and let its blocks be the blocks of the category of finite-dimensional representations. A block is nontrivial if it does not contain the trivial representation. Equivalence of nontrivial blocks. All blocks not containing the trivial representation are equivalent.
