The Supreme Court, Due Process and State Income Taxation of Trusts
What are the constitutional limits on a state\u27s power to tax a trust with no connection to the state, other than the accident that a potential beneficiary lives there? The Supreme Court of the United States will take up this question this term in the context of North Carolina Department of Revenue v. Kimberley Rice Kaestner 1992 Family Trust. The case involves North Carolina\u27s income taxation of a trust with a contingent beneficiary, meaning someone who is eligible, but not certain, to receive a distribution or benefit from the trust, who resides in that state. Part I of this Article explains the background of Kaestner Trust and frames the constitutional questions that will be before the Court at oral arguments on April 16, 2019. Part II examines how and why due process applies in the state income taxation context, with a particular emphasis on how familiar concepts of general and specific jurisdiction apply uneasily to donative trusts. Part III articulates the reasons that the Court should hold that a state has no constitutional authority to impose a tax on trust income where the trust\u27s only connection with the forum state is the residence of a contingent beneficiary. Kaestner Trust is the most important due process case involving trusts that the Court has decided in over sixty years; it bears directly on the fundamental meaning of due process
Superpotentials and Quiver Algebras for Semisimple Hopf Actions
We consider the action of a semisimple Hopf algebra on an -Koszul
Artin-Schelter regular algebra . Such an algebra is a
derivation-quotient algebra for some twisted superpotential , and
we show that the homological determinant of the action of on can be
easily calculated using . Using this, we show that the smash
product is also a derivation-quotient algebra, and use this to
explicitly determine a quiver algebra to which is Morita
equivalent, generalising a result of Bocklandt-Schedler-Wemyss. We also show
how can be used to determine whether the Auslander map is an
isomorphism. We compute a number of examples, and show how several results for
the quantum Kleinian singularities studied by Chan-Kirkman-Walton-Zhang follow
using our techniques
Universal trapping scaling on the unstable manifold for a collisionless electrostatic mode
An amplitude equation for an unstable mode in a collisionless plasma is
derived from the dynamics on the two-dimensional unstable manifold of the
equilibrium. The mode amplitude decouples from the phase due to the
spatial homogeneity of the equilibrium, and the resulting one-dimensional
dynamics is analyzed using an expansion in . As the linear growth rate
vanishes, the expansion coefficients diverge; a rescaling
of the mode amplitude absorbs these
singularities and reveals that the mode electric field exhibits trapping
scaling as . The dynamics for
depends only on the phase where is the derivative of the dielectric as

A Search for Radio Emission from the Young 16-ms X-ray Pulsar PSR J0537-6910
PSR J0537-6910 is a young, energetic, rotation-powered X-ray pulsar with a
spin period of 16 ms located in the Large Magellanic Cloud. We have searched
for previously undetected radio pulsations (both giant and standard) from this
pulsar in a 12-hour observation taken at 1400 MHz with the Parkes 64-m radio
telescope. The very large value of the magnetic field at the light cylinder
radius suggests that this pulsar might be emitting giant radio pulses like
those seen in other pulsars with similar field strengths. No radio emission of
either kind was detected from the pulsar, and we have established an upper
limit of ~ 25 mJy kpc^2 for the average 1400-MHz radio luminosity of PSR
J0537-6910. The 5-sigma single-pulse detection threshold was ~ 750 mJy for a
single 80-us sample. These limits are likely to be the best obtainable until
searches with greatly improved sensitivity can be made with next-generation
radio instruments.Comment: 4 pages, including 1 figure and 2 tables. Accepted for publication in

Nonlinear saturation of electrostatic waves: mobile ions modify trapping scaling
The amplitude equation for an unstable electrostatic wave in a multi-species
Vlasov plasma has been derived. The dynamics of the mode amplitude is
studied using an expansion in ; in particular, in the limit
, the singularities in the expansion coefficients are
analyzed to predict the asymptotic dependence of the electric field on the
linear growth rate . Generically , as
, but in the limit of infinite ion mass or for
instabilities in reflection-symmetric systems due to real eigenvalues the more
familiar trapping scaling is predicted.Comment: 13 pages (Latex/RevTex), 4 postscript encapsulated figures which are
