A characterization of balls using the domain derivative. <i>Electronic Journal of Differential Equations, 2006</i>(154), pp. 1-5.1072-6691https://hdl.handle.net/10877/14027In this note we give a characterization of balls in ℝN using the domain derivative. As a byproduct we will show that an overdetermined Stekloff eigenvalue problem is solvable if and only if the domain of interest is a ball.Text5 pages1 file (.pdf)enAttribution 4.0 InternationalDomain derivativeOverdetermined problemsStekloff problemArticle
