Variational problems on classes of convex domains | | Nicolas Van Goethem
; | | Date: |
25 Mar 2007 | | Journal: | Communications in Applied Analysis 8 n. 3 (2004) 353-371 | | Subject: | Optimization and Control | | Abstract: | We prove the existence of minimizers for functionals defined over the class of convex domains contained inside a bounded set D of R^N and with prescribed volume. Some applications are given, in particular we prove that the eigenvalues of differential operators of second and fourth order with non-constant coefficients as well as integral functionals depending on the solution of an elliptic equation can be minimized over this class of domains. Another application of this result is related to the famous Newton problem of minimal resistance. In general, all the results we shall develop hold for elliptic operators of any even order larger that 0. | | Source: | arXiv, math/0703734 | | Services: | Forum | Review | PDF | Favorites | |
