摘要：

This work examines whether evolving wormhole solution is possible or not in f(R,T) modified gravity theory. In the background of inhomogeneous FLRW-type wormhole configuration, the field equations are investigated for different choices of scale factors and shape functions. For the power law and exponential choice of the scale factor from cosmological context and decoupled power law of f(R,T) in each variable, wormhole configuration has been examined for two viable choices of shape function. Energy conditions are examined graphically for a range of values of the parameters involved. Finally, the possibility of emergent scenario at early cosmic evolution has been examined.
