  text: 'The Birkhoff conjecture says that the boundary of a strictly convex integrable
    billiard table is necessarily an ellipse. In this article, we consider a stronger
    notion of integrability, namely, integrability close to the boundary, and prove
    a local version of this conjecture: a small perturbation of almost every ellipse
    that preserves integrability near the boundary, is itself an ellipse. We apply
    this result to study local spectral uniqueness of ellipses using the connection
    between the wave trace of the Laplacian and the dynamics near the boundary and
    establish local uniqueness for almost all of them.'

  text: The Benjamin–Ono equation is shown to be well-posed, both on the line and
    on the circle, in the Sobolev spaces H^s for s > -1/2. The proof rests on a new
    gauge transformation and benefits from our introduction of a modified Lax pair
    representation of the full hierarchy. As we will show, these developments yield
    important additional dividends beyond well-posedness, including (i) the unification
    of the diverse approaches to polynomial conservation laws; (ii) a generalization
    of Gérard’s explicit formula to the full hierarchy; and (iii) new virial-type
    identities covering all equations in the hierarchy.

  text: We consider billiards obtained by removing from the plane finitely many strictly
    convex analytic obstacles satisfying the non-eclipse condition. The restriction
    of the dynamics to the set of non-escaping orbits is conjugated to a subshift,
    which provides a natural labeling of periodic orbits. We show that under suitable
    symmetry and genericity assumptions, the Marked Length Spectrum determines the
    geometry of the billiard table.

  text: We define and study the existence of very stable Higgs bundles on Riemann
    surfaces, how it implies a precise formula for the multiplicity of the very stable
    components of the global nilpotent cone and its relationship to mirror symmetry.
    The main ingredients are the Bialynicki-Birula theory of C∗-actions on semiprojective
    varieties, C∗ characters of indices of C∗-equivariant coherent sheaves, Hecke
    transformation for Higgs bundles, relative Fourier–Mukai transform along the Hitchin
    fibration, hyperholomorphic structures on universal bundles and cominuscule Higgs
    bundles.

  text: We derive rigorously the leading order of the correlation energy of a Fermi
    gas in a scaling regime of high density and weak interaction. The result verifies
    the prediction of the random-phase approximation. Our proof refines the method
    of collective bosonization in three dimensions. We approximately diagonalize an
    effective Hamiltonian describing approximately bosonic collective excitations
    around the Hartree–Fock state, while showing that gapless and non-collective excitations
    have only a negligible effect on the ground state energy.

  text: We consider the Korteweg–de Vries equation with white noise initial data,
    posed on the whole real line, and prove the almost sure existence of solutions.
    Moreover, we show that the solutions obey the group property and follow a white
    noise law at all times, past or future. As an offshoot of our methods, we also
    obtain a new proof of the existence of solutions and the invariance of white noise
    measure in the torus setting.

  text: 'Among the major mathematical approaches to mirror symmetry are those of Batyrev-Borisov
    and Stromdnger-Yau-Zaslow (SYZ). The first is explicit and amenable to computation
    but is not clearly related to the physical motivation; the second is the opposite.
    Furthermore, it is far from obvious that mirror partners in one sense will also
    be mirror partners in the other. This paper concerns a class of examples that
    can be shown to satisfy the requirements of SYZ, but whose Hodge numbers are also
    equal. This provides significant evidence in support of SYZ. Moreover, the examples
    are of great interest in their own right: they are spaces of flat SLr-connections
    on a smooth curve. The mirror is the corresponding space for the Langlands dual
    group PGLr. These examples therefore throw a bridge from mirror symmetry to the
    duality theory of Lie groups and, more broadly, to the geometric Langlands program.'
