Evolving wormhole solutions in f(R,T)=αR^m+βT gravity are shown to satisfy the null, weak, strong, and dominant energy conditions for tuned parameters, avoiding exotic matter at the throat.

abstract
In this present work, we have studied the traversable wormhole geometries in $f(R,T)$ gravity theory, where $R$ denotes the Ricci scalar and $T$ is the trace of the energy-momentum tensor. Firstly, two new shape functions are obtained for some assumed generating function. Also, some new generating functions are obtained in wormhole geometry for some well known shape functions and redshift functions. Energy conditions are examined in each wormhole solution and it is found that a particular type of wormhole satisfies all the energy conditions in a region.
