Machine learning in sentiment reconstruction of the simulated stock market
Mikhail Goykhman, Ali Teimouri
In this paper we continue the study of the simulated stock market framework defined by the driving sentiment processes. We focus on the market environment driven by the buy/sell tr…
Entropy of non-local gravity
Ali Teimouri
For higher derivative theories of gravity, it is possible to write the action in terms of auxiliary fields. In such case, one can show that the equations of motion for both actions…
Scale of non-locality for a system of particles
Spyridon Talaganis, Ali Teimouri
Higher derivative theories of gravity are associated with a mass scale to insure the correct dimensionality of the covariant derivatives. This mass scale is known as the scale of n…
Rotating black hole and entropy for modified theories of gravity
Spyridon Talaganis, Ali Teimouri
In this paper we obtain the entropy of the Kerr black hole for a number of modified theories of gravity. We show that as long as the deviation from Einstein Hilbert term consists p…
Entropic f(R) Gravity
Ali Teimouri
In this short paper we follow the entropic gravity approach and demonstrate how \(f(R)\) theories of gravity can be emergent. This is done by introducing an effective gravitational…
Hamiltonian Analysis for Infinite Derivative Field Theories and Gravity
Spyridon Talaganis, Ali Teimouri
Typically higher-derivative theories are unstable. Instabilities manifest themselves from extra propagating degrees of freedom, which are unphysical. In this paper, we will investi…
