Theorem

Proof This is equivalent to:

which on substituting
becomes

The equivalence follows from the identity

Littlewood's Other Conjecture Conjecture (1966) There is some

so that for all z on the boundary of the unit disc

Littlewood, in part, based his conjecture on computations
of
all such polynomials up to degree twenty.
Odlyzko has now done 200 MIPS years of computing
on this problem
