Abstract

We investigate projective modules of the reduced enveloping superalgebra \( U_{\chi }(\frak {g}) \) of the Lie superalgebra \( \frak {g}\) of Witt type with p-character χ of height at most one. We give a formula for the Cartan invariants of \( U_{\chi }(\frak {g}) \) which implies that \( U_{\chi }(\frak {g}) \) has only one block.
