MOND and cosmological issues from entropic gravity and nonextensive thermostatistics correspondence

It is an old idea to realize Einstein's equations as a thermodynamical equation of state. Hence, to understand the actual role of the holographic screen is a very relevant issue. In this letter we have analyzed the entropy as a function of the holographic screen in some different scenarios and...

Description
Summary:It is an old idea to realize Einstein's equations as a thermodynamical equation of state. Hence, to understand the actual role of the holographic screen is a very relevant issue. In this letter we have analyzed the entropy as a function of the holographic screen in some different scenarios and calculated a modified Newton's gravitational law for each one of them. We have also disclosed the modified Newtonian dynamics (MOND) from Verlinde's ideas. Besides, we have calculated some cosmological elements using the same concepts.
