Unsolved Problems in Visibility Graphs of Points, Segments and Polygons
Subir Kumar Ghosh, Partha Pratim Goswami
In this survey paper, we present open problems and conjectures on visibility graphs of points, segments and polygons along with necessary backgrounds for understanding them.
Black Hole Entropy: From Shannon to Bekenstein
Subir Ghosh
In this note we have applied directly the Shannon formula for information theory entropy to derive the Black Hole (Bekenstein-Hawking) entropy. Our analysis is semi-classical in na…
Towards a Discrete Spacetime
Sudipta Das, Subir Ghosh
A formalism is proposed to generate (the first step of) a discrete spacetime: spacetime with an inbuilt length scale. We follow the celebrated Landau theory of liquid - solid phase…
Noncommutative Spacetime in Very Special Relativity
Sudipta Das, Subir Ghosh, Salvatore Mignemi
Very Special Relativity (VSR) framework, proposed by Cohen and Glashow [1], demonstrated that a proper subgroup of the Poincaré group, (in particular ISIM(2)), is sufficient to des…
Planck Scale Effect in the Entropic Force Law
Subir Ghosh
In this note we generalize the quantum uncertainty relation proposed by Vancea and Santos [7] in the entropic force law, by introducing Planck scale modifications. The latter is in…
