  text: Using the Pauli-Fierz model of non-relativistic quantum electrodynamics, we
    calculate the binding energy of an electron in the field of a nucleus of charge
    Z and in presence of the quantized radiation field. We consider the case of small
    coupling constant α, but fixed Zα and ultraviolet cut-off Λ. We prove that after
    renormalizing the mass the binding energy has, to leading order in α, a finite
    limit as Λ goes to infinity; i.e., the cut-off can be removed. The expression
    for the ground state energy shift thus obtained agrees with Bethe's formula for
    small values of Zα, but shows a different behavior for bigger values.

  text: We consider the time evolution of N bosonic particles interacting via a mean
    field Coulomb potential. Suppose the initial state is a product wavefunction.
    We show that at any finite time the correlation functions factorize in the limit
    N → ∞. Furthermore, the limiting one particle density matrix satisfies the nonlinear
    Hartree equation. The key ingredients are the uniqueness of the BBGKY hierarchy
    for the correlation functions and a new apriori estimate for the many-body Schrödinger
    equations.

  text: In this paper we consider the topological side of a problem which is the analogue
    of Sen's S-duality testing conjecture for Hitchin's moduli space M of rank 2 stable
    Higgs bundles of fixed determinant of odd degree over a Riemann surface ∑. We
    prove that all intersection numbers in the compactly supported cohomology of M
    vanish, i.e. &quot;there are no topological L2 harmonic forms on M&quot;. This
    result generalizes the well known vanishing of the Euler characteristic of the
    moduli space of rank 2 stable bundles N of fixed determinant of odd degree over
    ∑. Our proof shows that the vanishing of all intersection numbers of H* cpt(M)
    is given by relations analogous to the Mumford relations in the cohomology ring
    of N.

  suggesting Problem 1, and for his help and \r\n encouragement. I am grateful to
  Michael Thaddeus for his inspiring paper [Thai], enlightening communications and
  his constant interest in my work. I am also indebted to Manfred Lehn for the idea
  of the proof of Theorem 6.2. I have found\r\nconversations with Michael Atiyah,
  Frances Kirwan and Graeme Segal very stimulating. I thank the Mathematical Institute
