To this end, we utilize standard techniques from calculus of variations, and some basic properties of Sobolev spaces. We compare our results with previously established ones. In an application, we analyze the determinants of timing of technological adoption, under linearly expanding technological frontier.vi, 34 leavesEnglishinfo:eu-repo/semantics/openAccessMulti-stage Optimal ControlSobolev SpacesAdoptionOptimal GrowthQA323 .D64 2007Sobolev spaces.Thesis
