Abstract Wormholes are geometrical constructions that appear in Einstein s general relativity eld equa tions They connect two distant regions of one or two space time through their shortcut ways Thisproperty can be used for rapid data communiucation or space travelling and So are very attractiveto physicists The matter supporting wormholes violates known energy conditions Some similar en ergy density is needed to deal accelarating in ation of universe and called dark energy In this thesissome solution to Einstein s general relativity eld equations is obtained that leads to wormholes inspherical and cylindrical coordinates and their energy tension tensor meets dark energy de nition
