Query: On central extensions of simple differential algebraic groups   We consider central extensions $Z\hookrightarrow E\twoheadrightarrow G$ in
the category of linear differential algebraic groups. We show that if $G$ is
simple non-commutative and $Z$ is unipotent with the differential type smaller
than that of $G$, then such an extension splits. We also give a construction of
central extensions illustrating that the condition on differential types is
important for splitting. Our results imply that non-commutative almost simple
linear differential algebraic groups, introduced by Cassidy and Singer, are
simple.
