    Parabolic Sandwiches for Functions on a Compact Interval and an Application to Projectile Motion by Robert Kantrowitz, Michael M. Neumann

    Published 2019-01-01
    “…About a century ago, the French artillery commandant Charbonnier envisioned an intriguing result on the trajectory of a projectile that is moving under the forces of gravity and air resistance. In 2000, Groetsch discovered a significant gap in Charbonnier’s work and provided a valid argument for a certain special case. …”

    From the Schwarzschild Anti-de Sitter Black Hole to the Conformal Field Theory by Akram Sadat Sefiedgar

    Published 2015-01-01
    “…In this letter, we investigate a possible modification to the thermodynamics of Schwarzschild anti-de Sitter (SAdS) black holes due to rainbow gravity model. Using the correspondence between a (d+1)-dimensional SAdS black hole and a conformal filed theory in d-dimensional spacetime, one may find the corrections to the Cardy-Verlinde formula from the modified thermodynamics of the black hole. …”

    Thermodynamics of Acoustic Black Holes in Two Dimensions by Baocheng Zhang

    Published 2016-01-01
