for the
infinite GUE is given in
terms of a Fredholm determinant by
where
is the integral operator on
with kernel
(
denotes the Bessel function) and b=1. Furthermore
(here the mean eigenvalue spacing is
), where
satisfies
the non-linear equation
with b=1, subject to the boundary condition
with b=1 (the parameter b is included above for later convenience).
Note that with b=0 (2.7) reduces to (2.2).
