Duke Mathematical Journal, 105(1), 25-58.http://hdl.handle.net/1773/2203We show that in some planar domains both extrema of the second Neumann eigenfunction lie strictly inside the domain. The main technical innovation is the use of "fiber Brownian motion," a process which switches between two-dimensional and one-dimensional evolution.272426 bytesapplication/pdfen-USPlanar Brownian motionNeumann eigenfunctionsfiber Brownian motionFiber Brownian motion and the "hot spots" problemArticle
