I review recent results on the procedure of integrating out unwanted degrees of freedom from a fundamental microscopic\u00a0string field theory action. A\u00a0first application is the construction of effective actions\/potentials for the strings’ light fields by integrating out massive string fields.\u00a0 I will\u00a0give a few examples of D-branes effective potentials obtained in this way. A second, physically different, application concerns analytic classical solutions of open string field\u00a0theory (OSFT) describing generic D-brane systems in a given closed string background. This time, by integrating out peculiar “pure gauge” degrees of freedom, we can precisely relate the action for fluctuations on the classical solution to the OSFT\u00a0directly formulated on the new background thus explicitly realizing (open string) background independence. I end up discussing possible new directions for future explorations.<\/p>\n\n\n\n
