    We study irreducible Smale spaces with totally disconnected stable sets and their associated (Formula presented.)-theoretic invariants. Such Smale spaces arise as Wieler solenoids, and we restrict to those arising from ...
  • Escher, J.; Guidotti, P.; Walker, C. (Zürich : European Mathematical Society Publishing House, 2013)
    The free boundary problem of a two phase flow in a rotating Hele-Shaw cell with Coriolis effects is studied. Existence and uniqueness of solutions near spheres is established, and the asymptotic stability and instability ...
  • Jahnel, J.; Loughran, D. (Cambridge : Cambrigde University Press, 2016)
    Given a number field k and a positive integer d, in this paper we consider the following question: does there exist a smooth diagonal surface of degree d in 3 over k which contains a line over every completion of k, yet ...
  • Abe, T.; Barakat, M.; Cuntz, M.; Hoge, T.; Terao, H. (Zürich : European Mathematical Society Publishing House, 2016)
    A Weyl arrangement is the arrangement defined by the root system of a finite Weyl group. When a set of positive roots is an ideal in the root poset, we call the corresponding arrangement an ideal subarrangement. Our main ...
  • Hempel, R.; Kohlmann, M. (Zürich : European Mathematical Society Publishing House, 2011)
    We study some spectral properties of a simple two-dimensional model for small angle defects in crystals and alloys. Starting from a periodic potential V:R2→R, we let Vθ(x,y)=V(x,y) in the right half-plane {x≥0} and Vθ=V∘M−θ ...
  • Lippoth, F.; Prokert, G. (Zürich : European Mathematical Society Publishing House, 2016)
    Within the framework of variational modelling we derive a two-phase moving boundary problem that describes the motion of a semipermeable membrane separating two viscous liquids in a fixed container. The model includes the ...
  • Rizzi, L.; Silveira, P. (Cambridge : Cambrigde University Press, 2017)
    For a fat sub-Riemannian structure, we introduce three canonical Ricci curvatures in the sense of Agrachev–Zelenko–Li. Under appropriate bounds we prove comparison theorems for conjugate lengths, Bonnet–Myers type results ...
  • Fahrenwaldt, M.A. (Cambridge : Cambrigde University Press, 2016)
    We develop an algebraic approach to constructing short-time asymptotic expansions of solutions of a class of abstract semilinear evolution equations. The expansions are typically valid for both the solution of the equation ...
  • Goffeng, M.; Schrohe, E. (Zürich : European Mathematical Society Publishing House, 2017)
    We study the spectral flow of Landau-Robin hamiltonians in the exterior of a compact domain with smooth boundary. This provides a method to study the spectrum of the exterior Landau-Robin hamiltonian's dependence on the ...
  • Goffeng, M.; Mesland, B.; Rennie, A. (Cambridge : Cambrigde University Press, 2016)
    We show how the fine structure in shift–tail equivalence, appearing in the non-commutative geometry of Cuntz–Krieger algebras developed by the first two listed authors, has an analogue in a wide range of other Cuntz–Pimsner ...
  • Hunsicker, E.; Roidos, N.; Strohmaier, A. (Zürich : European Mathematical Society Publishing House, 2014)
    In this paper we consider scattering theory on manifolds with special cusp-like metric singularities of warped product type g=dx2+x−2ah, where a>0. These metrics form a natural subset in the class of metrics with warped ...
  • Cordero, R.R.; Damiani, A.; Seckmeyer, G.; Riechelmann, S.; Labbe, F.; Laroze, D.; Garate, F. (Cambridge : Cambrigde University Press, 2013)
    We have used data from the Ozone Monitoring Instrument (OMI) aboard NASA's Earth Observing System (EOS) Aura satellite over the period 2004-11 to describe the characteristics of surface ultraviolet (UV) irradiance at ...
  • Broomhead, N.; Ottem, J.C.; Prendergast-Smith, A. (Cambridge : Cambrigde University Press, 2016)
    In this note we study properties of partially ample line bundles on simplicial projective toric varieties. We prove that the cone of q-ample line bundles is a union of rational polyhedral cones, and calculate these cones ...
  • Grübel, R.; Hitczenko, P. (Cambridge : Cambrigde University Press, 2013)
    Let Xi, i N, be independent and identically distributed random variables with values in N0. We transform ('prune') the sequence {X1, ⋯ , Xn}, n N, of discrete random samples into a sequence {0, 1, 2, ⋯ , Yn}, n ? N, of ...
  • Hagger, R. (Zürich : European Mathematical Society Publishing House, 2016)
    In this paper we derive an explicit formula for the numerical range of (non-selfadjoint) tridiagonal random operators. As a corollary we obtain that the numerical range of such an operator is always the convex hull of its ...
  • Escher, J.; Matioc, B.-V. (Zürich : European Mathematical Society Publishing House, 2011)
    We study the Muskat problem in a periodic geometry and incorporate capillary as well as gravity effects in the modelling. The problem is rewritten as an abstract evolution equation. By analysing this evolution equation we ...
  • Ebeling, W.; Gusein-Zade, S.M. (Cambridge : Cambrigde University Press, 2016)
    An invertible polynomial in n variables is a quasi-homogeneous polynomial consisting of n monomials so that the weights of the variables and the quasi-degree are well defined. In the framework of the construction of mirror ...
  • Lippoth, F. (Zürich : European Mathematical Society Publishing House, 2016)
    We rigorously justify the quasistationary approximations of two moving boundary problems. We work out a systematic procedure to derive a priori estimates that allow to pass to the singular limit. The problems under our ...
  • Sauer, M.; Hauf, T.; Sakiew, L.; Chan, P.W.; Tse, S.-M.; Hupe, P. (Heidelberg : Springer Verlag, 2016)
    The safety and efficiency of air traffic are significantly affected by adverse weather. This holds especially in terminal maneuvering areas (TMA) where, in addition to the impact of weather itself, potential weather avoidance ...
  • Lippoth, F.-M. (Zürich : European Mathematical Society Publishing House, 2011)
    We introduce the notion of maximal solutions of a class of moving boundary problems in the sense that we characterize what inhibits global existence of solutions. The technique is demonstrated on a model describing the ...
