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…
