We apply the spacetime dependent lagrangian formalism [1] to the action in general relativity. We obtain a Barriola-Vilenkin type monopole solution by exploiting the electrogravity duality of the vacuum Einstein equations and using a modified definition of empty space. An upper bound is obtained on the monopole mass M, M ≤ e(1−α)/α/(1 − α)2G where α = 2k is… CONTINUE READING
