Turning points of massive particles in Schwarzschild geometry

J. Polonyi, A. Radosz, A. Siwek +1

The stable geodesics in Schwarzschild geometry can not approach the center closer than the radius of the photon sphere, 3/2 times the Schwarzschild radius. In other words, massive…

The Doppler shift in a Schwarzschild spacetime

A. Radosz, A. T. Augousti, K. Ostasiewicz

We demonstrate that in the case of Schwarzschild spacetime the Doppler shift is partially factorized into terms representing relativistic, kinematical and the gravitational contrib…

Decoupling of kinematical time dilation and gravitational time dilation in particular geometries

A. Radosz, A. T. Augousti, K. Ostasiewicz

Two different forms of time dilation, namely, the kinematical time dilation of special relativity and gravitational red shift are coupled during observations of systems moving thro…

Doppler effect in Schwarzschild geometry

A. Radosz, A. T. Augousti, K. Ostasiewicz

The Doppler shift considered in general relativity involves mixed contributions of distinct, gravitational and kinematical origins and for most metrics or trajectories it takes a c…

Integrating economic and psychological insights in binary choice models with social interactions

Katarzyna Ostasiewicz, Michal H. Tyc, Piotr Goliczewski +3

We investigate a class of binary choice models with social interactions. We propose a unifying perspective that integrates economic models using a utility function and psychologica…
