Properties of the Concrete distribution
David D. K. Chow
We examine properties of the Concrete (or Gumbel-softmax) distribution on the simplex. Using the natural vector space structure of the simplex, the Concrete distribution can be reg…
Schlömilch integrals and probability distributions on the simplex
David D. K. Chow
The Schlömilch integral, a generalization of the Dirichlet integral on the simplex, and related probability distributions are reviewed. A distribution that unifies several generali…
Rotating Strings in Six-Dimensional Higher-Derivative Supergravity
David D. K. Chow, Yi Pang
We construct the first rotating string solution in 6-dimensional Einstein-Gauss-Bonnet supergravity, carrying both electric and magnetic charges. By embedding the known rotating st…
Characterization of three-dimensional Lorentzian metrics that admit four Killing vectors
David D. K. Chow
We consider three-dimensional Lorentzian metrics that locally admit four independent Killing vectors. Their classification is summarized, and conditions for characterizing them are…
On Late Time Tails in an Extreme Reissner-Nordström Black Hole: Frequency Domain Analysis
Srijit Bhattacharjee, Bidisha Chakrabarty, David D. K. Chow +2
In this brief note, we revisit the study of the leading order late time decay tails of massless scalar perturbations outside an extreme Reissner-Nordström black hole. Previous auth…
Conformal isometry of the six-dimensional black string and dualities of null geodesics
David D. K. Chow
We show that the extreme six-dimensional black string admits a conformal isometry under inversion. Duality relations between null geodesics of various brane geometries are demonstr…
