Abstract
Dynamics of thin-shell wormholes within the context of f(R)gravity by joining two identical copies of Reissner–Nordstrom–de Sitter manifold using the cut and paste approach is discussed. The stability of wormholes is analyzed through the radial perturbation about the static solution and the modified generalized Chaplygin gas equation of state (EoS). This formalism gives rise two specific different configurations of f(R) gravity, in which quadratic type model and cubic type model. The presence of both stable and unstable regions depending on the appropriate values of different parameters are examined their EoS, with taken into account severalf(R)gravity models as well as the metric space are illustrated.
Also, the stability regions under the radial perturbation depend on the EoS parameter β2 usually is explained as the subluminal square speed of sound exist. Such a region of stability in the existence of a large value of the charge is significantly is increased and extended by decreasing the value of the cosmological constant The effect of increasing dark sources δ and α parameters leads to an increase in the stable regions is displayed. Stability regions increase for increasing EoS parameters γ,ς,η and also the influence of the curvature parameter R may increase the stability regions.
