Somewhat less well understoo d are the nodal sets of their restrictions to the boundary\, that is\, the eigenfunctions of the Dirichlet-to-Neumann operator. In particular\, litt le is known about nodal counts. In this talk we explore this problem and p rove an asymptotic version of Courant’s nodal domain theorem for Dirichlet -to-Neumann eigenfunctions. This is joint work with Asma Hassannezhad (Bri stol).\n\nSeminar Spectral Geometry\n Visit the Web site: https://archimede .mat.ulaval.ca/agirouard/SpectralClouds/\n DTSTART:20211129T170000Z DTEND:20211129T180000Z SUMMARY:David Sher (DePaul University) URL:/mathstat/channels/event/david-sher-depaul-univers ity-335167 END:VEVENT END:VCALENDAR
