Abstract
The evolution of density perturbations around cosmic strings in the matter-dominated era is discussed with attention to the specific nature of string perturbations. The parameter Gμ is calculated in two completely independent ways—from the requirements that Abell clusters are formed and that the galaxy-galaxy correlation function matches the observed one. Both values are consistent, lending support to the cosmic string theory.Keywords
