• Dispersive effects of weakly compressible and fast rotating inviscid fluids 

  Ngo V.-S; Scrobogna S. (Discrete and Continuous Dynamical Systems - Series A, 2017-08)

  We consider a system describing the motion of an isentropic, inviscid, weakly compressible, fast rotating fluid in the whole space $\mathbb{R}^3$, with initial data belonging to $ H^s \left( \mathbb{R}^3 \right), s>5/2 $. ...

• On pointwise and weighted estimates for commutators of Calderón-Zygmund operators 

  Lerner A. K; Ombrosi S.; Rivera-Ríos I. P. (Advances in Mathematics, 2017)

  In recent years, it has been well understood that a Calderón-Zygmund operator T is pointwise controlled by a finite number of dyadic operators of a very simple structure (called the sparse operators). We obtain a similar ...

• Optimally refined isogeometric analysis 

  Garcia D.; Bartoň M.; Pardo D. (Procedia Computer Science, 2017-06)

  Performance of direct solvers strongly depends upon the employed discretization method. In particular, it is possible to improve the performance of solving Isogeometric Analysis (IGA) discretizations by introducing multiple ...

• Automatic fitting of conical envelopes to free-form surfaces for flank CNC machining 

  Bo P.; Bartoň M.; Pottmann H. (Computer Aided Design, 2017-10)

  We propose a new algorithm to detect patches of free-form surfaces that can be well approximated by envelopes of a rotational cone under a rigid body motion. These conical envelopes are a preferable choice from the ...

• Universal bounds for large determinants from non-commutative Hölder inequalities in fermionic constructive quantum field theory 

  Bru J.-B.; de Siqueira Pedra W. (Mathematical Models and Methods in Applied Sciences (M3AS), 2017-08-02)

  Efficiently bounding large determinants is an essential step in non-relativistic fermionic constructive quantum field theory to prove the absolute convergence of the perturbation expansion of correlation functions in terms ...
