On a Boltzmann equation for Haldane statistics
The study of quantum quasi-particles at low temperatures including their
statistics, is a frontier area in modern physics. In a seminal paper F.D.
Haldane proposed a definition based on a generalization of the Pauli exclusion
principle for fractional quantum statistics. The present paper is a study of
quantum quasi-particles obeying Haldane statistics in a fully non-linear
kinetic Boltzmann equation model with large initial data on a torus. Strong L1
solutions are obtained for the Cauchy problem. The main results concern
existence, uniqueness and stability. Depending on the space dimension and the
collision kernel, the results obtained are local or global in time.Comment: 24 pages. arXiv admin note: text overlap with arXiv:1406.0265 This is
the published version of the paper. The condition (2.3) on the collision
kernel is strengthened, as required for the result to hol
Well-posedness of the Cauchy problem for a space-dependent anyon Boltzmann equation
A fully non-linear kinetic Boltzmann equation for anyons and large initial
data is studied in a periodic 1d setting. Strong L1 solutions are obtained for
the Cauchy problem. The main results concern global existence, uniqueness, and
stability.Comment: 22 pages. In this version an earlier error has been corrected, and
with it a study of the time asymptotics moved to a future paper. arXiv admin
