Query: Two functions on Sp(g,R)   We consider two functions on Sp(g,R) with values in the cyclic group of order
four {1,-1,i,-i}. One was defined by Lion and Vergne. The other is -i raised to
the power given by an integer valued function defined by Masbaum and the author
(initially on the mapping class group of a surface). We identify these
functions when restricted to Sp(g,Z). We conjecture the identity of these
functions on Sp(g,R).
