Abstract

In this paper, we are going to investigate a new perspective of the two-field inflation
model with respect to the swampland dS conjecture. At the first step, we study the two-fields
inflation model, and apply the swampland conjecture to our model. Then, we calculate some
cosmological parameters such as scalar spectrum index, tensor-to-scalar ratio, and compare our
results with the recent observational data. Also, we give numerical analysis to show agreement
with observational data.
