Abstract
The specific heat of then-vector model to lowest order in 1/n is analyzed when the dimensionality varies continuously betweend=3 andd=2. The changeover from three-dimensional to two-dimensional behavior is related to the location of the bare transition temperature with respect to the critical region.
