In this paper we introduce a numerical approach adapted to the minimization
of the eigenmodes of a membrane with respect to the domain. This method is
based on the combination of the Level Set method of S. Osher and J.A.
Sethian with the relaxed approach. This algorithm enables both changing the
topology and working on a fixed regular grid.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.
An OpenURL link contains article metadata and directs it to the
OpenURL server of your choice. The OpenURL server can provide access
to the resource and also offer complementary services (specific
search engine, export of references...). The OpenURL link can be
generated by different means.
If your librarian has set up your subscription with an
OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your
In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see
You should disable this module if you wish to use the OpenURL server that you or your library have defined.
