Physica A: Statistical Mechanics and its Applications, 1997, vol. 246, issue 3, 587-590
Abstract:
Exact lower bound on the correlation function and susceptibility are obtained in terms of the quantity r∗=r0+(12u/(2π)d)∫ ddl〈ϕlϕ−l〉, where 〈ϕlϕ−l〉 are the exact averages. Further lower bounds are obtained on r∗, relating it to an exactly soluble model.
