Abstract
It has been suggested that the cosmological constant is a variable dynamical quantity. A class of solution has been presented for the spherically symmetric space time describing wormholes by assuming the erstwhile cosmological constant to be a space variable scalar, viz., = . It is shown that the Averaged Null Energy Condition (ANEC) violating exotic matter can be made arbitrarily small.
