David Ruiz: <b><a href='/seminar/876/'>Sign-changing solutions to overdetermined elliptic problems in bounded domains.</a></b><br />
Centro de Giorgi, Sala Conferenze, 14:30<br />
</p>
<div style="font-size: smaller;"><p>In 1971 J. Serrin proved that, given a smooth bounded domain Ω ⊂ $R^N$ and u a positive solution of the problem:
</p>
<p>−∆u = f(u) in Ω, u = 0 on ∂Ω, ∂ν u = constant on ∂Ω,
</p>
<p> then \Omega is necessarily a ball and u is radially symmetric. In this paper we prove that the positivity of u is necessary in that symmetry result. In fact we find a sign-changing solution to that problem for a C<sup>2</sup> function f(u) in a bounded domain \Omega different from a ball. The proof uses a local bifurcation argument, based on the study of the associated linearized operator.</p>
