Abstract

The present status of the renormalization-group (RG) predictions on the superfluid density ρ_s and the specific heat C⁺ and C^- near the λ-line of ⁴He is briefly reviewed. Particular attention is given to universal amplitude ratios related to these quantities. The goals of a new theory project are presented that involves higher-order calculations of the amplitude functions of ρ_s, C⁺ and C^- which are of fundamental importance for a test of the universality predictions of the RG theory.
