Query: On the Finite-Time Blowup of a 1D Model for the 3D Axisymmetric Euler
  Equations   In connection with the recent proposal for possible singularity formation at
the boundary for solutions of 3d axi-symmetric incompressible Euler's equations
(Luo and Hou, 2013), we study models for the dynamics at the boundary and show
that they exhibit a finite-time blow-up from smooth data.
