Query: Topological complexity of motion planning and Massey products   We employ Massey products to find sharper lower bounds for the Schwarz genus
of a fibration than those previously known. In particular we give examples of
non-formal spaces $X$ for which the topological complexity $\TC(X)$ (defined to
be the genus of the free path fibration on $X$) is greater than the
zero-divisors cup-length plus one.
