    • As a function of g, 1/as increases monotonically from - inf for g -> 0+ to + inf for g -> inf. Beyond the two-body bound state threshold in vacuum (1/as=0), as is the ``size'' of this bound state with binding energy Eb = 1 / mas2; see Ref. [3].

    • The result is quite different for lattice fermions. In the U < 0 Hubbard model for | U | / t >> 1 the bosons have an effective mass U / t2 thus leading to a strong coupling Tcapp t2/ U. See, e.g.

    • Even in a purely bosonic system the dynamics of the order parameter will be damped sufficiently close to Tc [see, Sec. VI E]. Our analysis, however, is restricted to be valid only outside the critical region.

    • In this case a nonzero DELTA precludes a vanishing energy scale and the low frequency expansion of the effective action is well defined for all couplings.
