Electric potential of insulated conducting objects in presence of electric charges -- some exact and approximate results
Karlo Filipan, Hrvoje Štefančić
Determination of the electric potential of insulated conducting objects is an important problem both theoretically and practically. For an insulated conducting object in the presen…
Dark matter fluid constraints from galaxy rotation curves
Dalibor Perkovic, Hrvoje Stefancic
Galaxy rotation curves are considered to be convincing evidence for dark matter or some dynamically equivalent alternative mechanism. Starting only from the rotation curve data, we…
Causal motifs and existence of endogenous cascades in directed networks with application to company defaults
Irena Barjašić, Hrvoje Štefančić, Vedrana Pribičević +1
Motivated by the detection of cascades of defaults in economy, we developed a detection framework for an endogenous spreading based on causal motifs we define in this paper. We ass…
Purely kinetic k-essence description of barotropic fluid models
Dalibor Perkovic, Hrvoje Stefancic
Purely kinetic k-essence models have been shown in the literature to be a field theory equivalent of barotropic fluid models of dark energy or dark matter-dark energy unification.…
Bi-stability of SUDR+K model of epidemics and test kits applied to COVID-19
Vinko Zlatić, Irena Barjašić, Andrea Kadović +2
Motivated with various responses of world governments to COVID-19, here we develop a toy model of the dependence epidemics spreading on the availability of tests for disease. Our m…
Barotropic fluid compatible parametrizations of dark energy
Dalibor Perkovic, Hrvoje Stefancic
Parametrizations of Equation of state parameter as a function of the scale factor or redshift are frequently used in dark energy modeling. The question investigated in this paper i…
