摘要
En 中文
The reconstruction of a warm inflationary universe model from the scalar spectral index n(S)(N) and the tensor to scalar ratio r (N) as a function of the number of e-folds N is studied. Under a general formalism we find the effective potential and the dissipative coefficient in terms of the cosmological parameters n(S) and r considering the weak and strong dissipative stages under the slow roll approximation. As a specific example, we study the attractors for the index nS given by n(S) - 1 alpha N-1 and for the ratio r alpha N-2, in order to reconstruct the model of warm inflation. Here, expressions for the effective potential V(phi) and the dissipation coefficient Gamma(phi) are obtained.
