Query: An analogue of the Perelomov-Popov formula for the Lie superalgebra Q(N)   In this short note we study the center of the universal enveloping algebra of
the strange Lie superalgebra Q(N). We obtain an analogue of the well known
Perelomov-Popov formula (1968) for central elements of this algebra - an
expression of the central characters through the highest weight parameters.
