場 所: 自然学系棟D棟 509教室
講 演 者: Konstantin Pankrashkin 氏(University Paris-Sud)
題 目: ``On eigenvalues of a Laplacian with Robin boundary conditions"
講演要旨:
We are going to discuss the spectral problem
-\Delta u= E u, du/dn =B u
in smooth domains, with an attention to the situation when the parameter B
becomes large. We show that the problem essentially lives at the boundary
of the domain, and the contributions of various geometric characteristics
are shown. A link with Faber-Krahn-type inequalities is discussed.
