In this communication we have presented a com-
parative study of Friedmann-Lemaître-Robertson-Walker
(FLRW) cosmological models in alternative theory of grav-
ity with linearly varying deceleration parameter (LVDP)
and bilinearly varying deceleration parameter (BVDP) as
suggested by Mishra and Chand (Astrophys. Space Sci.
361:259, 2016c). The role of viscosity in cosmology have
been studied by several researchers. Under the influence of
such study we have also studied bulk viscous fluid cos-
mological models in alternative f (R, T ) theory of grav-
ity along with comparison of results by taking LVDP and
BVDP. The main conclusion of the paper is that BVDP law
provides better results in comparative with Berman’s con-
stant deceleration law (CDP) and LVDP law. Also the BVDP
law provides an envelope for CDP law and LVDP law.
