Query: Inflationary Cosmology with Quantum Gravitational Effects and the
  Swampland Conjectures   Recently proposed two swampland criteria that arising from string theory
landscape lead to the important challenge of the realization of single-field
inflationary models. Especially one of swampland criteria which implies a large
tensor-to-scalar ratio is strongly in tension with recent observational
results. In this paper, we explore the possibility if the swampland conjectures
could be compatible with single-field inflationary scenarios if the effects due
to the quantum theory of gravity are considered. We show that the quantum
gravitational effects due to the nonlinear dispersion relation provides
significant modifications on the amplitude of both the scalar and tensor
perturbation spectra. Such modifications could be either raise or reduce the
perturbation spectra depending on the values of the parameters in the nonlinear
terms of the dispersion relations. Therefore, these effects can reduce the
tensor-to-scalar ratio to a smaller value which helps to relax the tension
between the swampland conjecture and observational data.
