  • 100 years of Weyl's lawMathematical Analysis and Applications Seminar, Weizmann Institute of Science, Rehovot, Israel, May 8, 2012
  • 100 years of Weyl's lawJerusalem Analysis and PDEs seminar, Hebrew University at Jerusalem, Israel, May 17, 2012
    In 1911-1912 Hermann Weyl published 2 papers (more followed) describing distribution of eigenvalues of Dirichlet Laplacian in the bounded domain. These were one of the first Weyl's publications and the new exciting field of mathematics has been created.
    I will discuss
    • Weyl law with sharper remainder estimates (in particular, Weyl conjecture);
    • Generalized Weyl law;
    • When generalized Weyl law works and when it does not and how it should be modified;
    • What should be used instead of eigenvalue counting function when the spectrum is not necessarily discrete;
    • Weyl law and Thomas-Fermi theory.
  • Asymptotics of the ground state energy and related topics for heavy atoms and molecules, Séminaire: Problèmes Spectraux en Physique Mathématique, Institut Henri Poincaré, December 2, 2013
  • Eigenvalue Asymptotics for Dirichlet-to-Neumann Operator. Analysis and Geometry Seminar, Department of Mathematics, Northeastern University, November 15, 2014
